Over-thinking Glenn Campbell's Area 51 photograph - real - hoax - a rock?




Researcher/activist Glenn Campbell recently caused a ruckus by posting what he claimed were photos of some type of flying object taken on a recent hike up Tikaboo Peak that overlooks the worst kept secret- secret base in the world, the Groom Lake Test Flight Center also known as Area 51.

You can view the photo by visiting his website (see the link at the top right under "Cool New Links".

Also make sure you also visit the discussion forum at dreamlandresort.com and see the feeding feeding frenzy it sparked.

Opinions on what the photo showed varied from it being a UAV to a rock thrown up by one of the witnesses.

Some of the posters voiced envy, healthy skepticism and downright righteous-anger for and against Glenn Campbell - with some wanting to know what he was trying to pull - with others going to his defense - saying the forum was being unfair to him.

But it was interesting for me to note that no one did a logical and methodical analysis of the photo - so - not wanting to be left out of the fray - I have decided to step up.

Because the photo of the image belongs to Glenn, I will not post it here.

I'll preface my photo-forensics foray by stating over the last decade or so I have been training myself and experimenting in image analysis techniques which I have been called to use on many occasions (by various publications) to debunk UFO photographs, 9-11 (images) conspiracy theories and the like.

That said, with the advent of cheap and easy to use digital image editing software, its easier than ever to fake photographs showing anything one wants to show - be it an anonymous man captured standing on the top of the World Trade Center just seconds before a frame-frozen hijacked airliner flies through the building to the amateurish Photoshopping of an extra missile (because one failed to launch) into a photo released by the Iranian government to strike fear into the West and especially Israel. I was amazed when even seasoned photo editors at major newspapers missed that one.

As a result everyone is aware that long gone has been the assumption that photos don't lie - but it is safe to assume that people still do - especially those with a little Photoshop knowledge.

When I learned about the Campbell photo, and read the posts on Dreamland Resort - I decided what was needed was some intelligent analysis.


I downloaded the images off of Glenn's site and went to work. My first clue that the image was probably unaltered was that Glenn had made the raw image available , which includes the EXIF data (something most photo-fakers delete) because it reveals a huge amount of information about the image.

EXIF stands for: Exchangeable Image File Format and is now standard on most pro-sumer and high-end digital cameras.

It suffices to say it is a small data file attached to the image detailing the technical specifics of the image in question, such as camera type, date and time the image was taken, exposure mode, and sometimes (in higher end-GPS linked cameras) even the latitude and longitude where the photo was snapped.

The EXIF data can also reveal if the image was futzed with in Photoshop (or any other image editing program) when it was altered, including any changes in resolution, contrast, file formats etc.

Now you can see why the EXIF data is missing from most faked photographs. Without EXIF data to examine ,I will not sign off as a photo being authentic.

After looking at the EXIF data and the image itself, i posted this on Dreamland Resort:

It is interesting to note that Glenn is shooting at a very low DPI (72) which makes this image difficult to enhance or do much forensic evaluation on.

Plus- notice the focus distance to the object is 81 meters (approximately 240 feet) and not infinity - indicating the object is not very large or flying very high. The blurred movement also indicates that the object was either moving very fast or relatively-fast in relation to the camera.

if it is a real craft - and not a hoax- its small - like a mini UAV - maybe used for recon at our favorite non-existent air base.

My guess Glenn is sitting back chuckling to himself about every one's (including my) speculations.

Just not enough data here.

END SNIP



Since then - I have decided to expand on my post after doing a more thorough examination of the photo, applying a few image algorithms (and other important sounding words) I also decided to examine the provenance of the photographer as well.

I love a challenge and chance to hone my skills - even if it was expending a lot of time and energy on something that might turn out to be just a rock - but I wasn't doing anything important tonight anyway.

Although this is a long post - consider this a crash course on spotting photo fakery.

But first a word about EXIF.

Although the EXIF data from the raw image did not indicate it had been manipulated, through my experience in image analysis I have also found it is possible to edit the EXIF data as well, but that too leaves tale-tale signs that can be also be ferreted out.

First thing I did was to re-sample the image at a higher DPI using Genuine Fractals. This makes it easier to examine the pixel structure and look for any thing out of the ordinary.

Enhancing the contrast range between the highlights, mid-tones and shadows did reveal an interesting anomaly, some blurred streaked, pixels emanating from the flying object up toward the top of the frame. if you have Photoshop. play with the contrast controls on a magnified version of the image and you will see what I see.

The streaking indicates to me that the object was most likely falling straight down, much like a rock would when tossed up in the air.

Even though the EXIF data indicated the shutter speed used was 1/500 sec, it was not enough to freeze the relative motion of the object, which by all indications appears to be down.

However, there is another possible explanation for the streak. It could have been caused by heavy pressure by the photographer on the shutter button, causing the camera to move down slightly during the exposure - a natural photographic occurrence - which i have done myself when photographing lightning . sound logical right?

But then i got to thinking - putting myself on that peak and watching the object fly by and thought - if I was taking that photo I would be following the object in the viewfinder and panning with it which would negate the downward pressure from my shutter finger.

I took out my camera and reenacted the scenario (albeit on the balcony of my apartment) and could not recreate the downward streak.

But wait - maybe he had the camera on a tripod - I thought - that would account for the streak right? If the camera was locked down, on a tripod on unstable ground and there was enough pressure from the photographer's finger it might do that right?

But if that was the case, it could mean the image was staged, and Glenn was expecting the object to fly into the frame, or someone threw a rock up into the air and he was standing at the ready to snap it before it hit the ground.

To make a long post even longer ( and at the risk of over-thinking this entire non-story story and possibly doing exactly what Glenn wants us to do - pontificate about a rock ) I couldn't help but ask myself, what is wrong with this picture?

And I'm not referring to the weird shadow or the streak, or the fact the man looks like he just chunked something into the air.

I'm puzzled by Glenn's account of the sighting.

Although Glenn has amended his initial report with more details, some things don't sit right, like the vagueness of his description - as if he's afraid to say what it is. Like he has heavily weighed and qualified his description.

Glenn writes: "I cannot say what the triangular object is, but I guarantee that the photo itself is authentic and unretouched."
You can click on the image above to see it in maximum detail. -snip -

"Other than cropping the above image, I DID NOT ALTER IT IN ANY WAY. The witnesses to the sighting were myself and the two people shown above: a visitor from Utah, Kevin, and his 8-year-old son, John Charles.

Alien craft? Advanced military test vehicle? You decide." - as if he is daring the pundits too say what it is and then prove them wrong by revealing its true nature.

He wrote on Dreamland Resort: "The craft was virtually silent: no jet noise, no hum, no sonic boom. It was traveling roughly in a northwest direction (about the same vector at Highway 375 in the Tikaboo Valley). The trajectory was parabolic. The craft appeared to accelerate at approximately 1G during flight, which would have made it nearly weightless. The occupants, if any, would have experienced almost no gravity until the end of the journey, when they would have been crushed by the accumulated inertia (at least according to Earth physics). No human could be piloting that craft and survive. Who then?"

Think about it - what Glenn described above could also pertain to - yes - a rock thrown by someone, silent, parabolic arc that sudden stop at the end of its flight crushing any occupants (insects?) that may be onboard.

In any event and before passing judgement, I'd like to hear from his other witnesses. I'd like to see the shots he took before and after the photo in question. There must be others- everyone poses for a picture on Tikaboo don't they?

In the end - it caused a stir - sent more traffic to his blog - and put Glenn back on the map after a long absence.

I can't help but think of the late great Paul Newman's last line from The Color of Money - "I'm back!"

Way to go Glenn.

When do you jump out and say "I never did say it wasn't a rock."

-Steve Douglass


UPDATE: It IS a rock.

See the link at the top right.

Glenn "Goober" Campbell can now have the great satisfaction of thumbing his nose at all the experts - including me - but he did so at the expense of his credibility.

Just like a little kid who keeps sticking his tongue out at you - don't you just want to pop him?

Can't take the heat? Fight in Afghanistan.


By Amir Shah - The Associated Press
Posted : Tuesday Oct 14, 2008 12:03:14 EDT
KABUL, Afghanistan — U.S. military successes in Iraq have forced sophisticated and well-trained insurgents to pour into Afghanistan instead, the Afghan defense minister said Tuesday.

Gen. Abdul Rahim Wardak, said terrorists who would have once fought in Iraq have been “diverted” to Afghanistan.

“The success of coalition forces in Iraq and also some other issues in some of the neighboring countries have made it possible that there is a major increase in the foreign fighters,” Wardak told a news conference. “There is no doubt that they are [better] equipped than before. They are well trained, more sophisticated, their coordination is much better.”

The top U.S. commander in eastern Afghanistan, Maj. Gen. Jeffrey Schloesser, said last month that he is seeing a spike in the number of foreign militants — including Arabs and Chechens — flowing into Afghanistan. He said militant Web sites have been encouraging fighters to go to Afghanistan instead of Iraq.

“I can’t prove they are coming from Iraq to Afghanistan, but I’ve seen it on Web sites that that’s what they’re being told to do,” Schloesser said.

Violence has risen steadily in Afghanistan since late 2005. More than 4,700 people — mostly militants — have been killed in insurgency related-violence this year, according to an Associated Press count of figured provided by Afghan and western officials.

U.S.-led troops killed five insurgents in central Ghazni province Monday during a raid to disrupt a foreign fighter network, the coalition said Tuesday.

The coalition also said one of its service members was killed and several others were wounded in southern Afghanistan on Monday when their vehicle was hit by a roadside bomb. No other information, including the service members’ nationalities or precise location of the attack, was released.

Blackswift cancelled or turned black?


Editors note: According to an article in Aviation Week & Space Technology Magazine, DARPA'S hypersonic aircraft study, Blackswift has been cancelled. My guess it has not been cancelled but has retreated into the black world because the technology behind the aircraft platform is as revolutionary as Low Observable (stealth) technology and thus now labeled as highly-classified. Coming soon to a non-existent test base in Nevada - Blackswift - redux.

AVW article follows: :

BLACKSWIFT canceled by the U.S. Defense Advanced Research Projects Agency (DARPA) after Congress slashed the program’s fiscal 2009 budget to $10 million, from $120 million.

Blackswift was to demonstrate an unmanned hypersonic vehicle able to take off, accelerate to a Mach 6 cruise and return to a runway landing.

“Congress made significant reductions in the amount of funds available to DARPA and the Air Force for the Blackswift testbed,” the agency said in a statement. “Based on this, DARPA determined that it would not be possible to proceed with the solicitation for the effort.”

DARPA had hoped to award a contract for the demonstrator later this year, and was believed to be negotiating with a Lockheed Martin Skunk Works-led team that included Boeing. The Blackswift was expected to fly in 2012. Meanwhile, DARPA says it will continue with the Falcon program to fly unpowered hypersonic test vehicles in 2009.

Congress was skeptical of Blackswift’s technical achievability and operational utility, cutting DARPA FY ‘09 funding from the requested $70 million to $10 million and eliminating the Air Force’s requested $50 million for the joint program.

“Obviously we are disappointed that we will not have the appropriated funds to move forward with the Blackswift flight test,” DARPA program manager Steven Walker said. He said a significant effort had been made to develop the propulsion technology and build a national government and industry team capable of developing and flying a reusable hypersonic testbed.

“The Blackswift testbed would have been able to take off under its own power, cruise at Mach 6, maneuver at hypersonic speeds and land, and then do it again,” Walker said. “Blackswift, or something very much like it, will be a required step prior to the U.S. developing an operational, reusable air-breathing hypersonic airplane.”

Blackswift was to be powered by turbine-based combined-cycle engines using a high-Mach turbojet to take the vehicle from standstill to the speed at which a dual-mode ramjet/scramjet took over and accelerated it to Mach 6. The turbojet and scramjet engines were to share inlets and nozzles.

Under DARPA’s Falcon program, Lockheed Martin is building two unpowered HTV-2 test vehicles, which will be launched by Orbital Sciences Minotaur boosters to demonstrate aerodynamic and structural technology for sustained hypersonic flight.

Brit's Lurker Bomb/Fire Shadow


The lurker bomb can hover for ten hours... and then strike its target in the space of a minute
By PETER ALMOND/London Times

A revolutionary missile that can stalk a target until the perfect moment to strike is being developed by the Ministry of Defence for use against the Taliban in Afghanistan.

The so-called lurker bomb will also be able to shadow British troops for up to ten hours or 100 miles, ready to take out enemy targets with surgical precision at a minute’s notice.

The 12ft weapon – officially named Fire Shadow and made in Britain by leading missile manufacturer MBDA – will be operated by the Royal Artillery.

It made its first test flight in Wales earlier this year and is expected to be operational by 2010.

One of the biggest problems facing British troops in Afghanistan is Taliban ambushes. The insurgents often escape before a counter-attack can be launched because they know the Afghan terrain well, it takes time for air support to arrive, and the British are reluctant to use existing powerful missiles for fear of causing collateral damage such as killing civilians or flattening homes.

Fire Shadow’s ability to ‘stooge’ above the troops means it can be guided to a target within seconds. And its deadly precision requires only a small warhead of 50lb, compared with the RAF’s smallest bomb of 500lb.

The Army wants to be able to fire salvos of Fire Shadows, having several in the air at once to hit multiple targets. The missiles, also known as ‘loitering munitions’, are expected to replace some RAF patrols.

Fire Shadow can be guided to its target by troops on the ground with lasers, by operators in aircraft or helicopters, or by the Army’s new Watchkeeper surveillance drone.


Once airborne, however, Fire Shadow is unable to return to base. If it is not used in action, it is brought down in a controlled crash after it runs out of fuel.

Akram Ghulam, head of loitering munitions at MBDA in Stevenage, Hertfordshire, said: ‘I can see these being used where small, surgically precise effects will have greater utility than an artillery shell or a bomb.’

MBDA leads the Fire Shadow development team, which cost the MoD £74million in its first year. It includes British firms Qinetiq, Thales and Roxcel, and several smaller and academic organisations.

The concept of a lurker bomb is the cornerstone of the MoD’s Indirect-Fire Precision Attack project. Fire Shadow is one of six projects that include an artillery shell that can electronically ‘sense’ its target, a new anti-aircraft missile for the Royal Navy, and advanced guidance for the new Guided Multiple Launch Rocket System (GMLRS).

The first GMLRS batteries have already been in action in Afghanistan’s Helmand area where British troops are operating. Nicknamed the 70km sniper – the rocket’s maximum range – about 250 precision-guided rockets have been fired so far this year, according to an MoD spokesman. At £60,000 a rocket that works out at £15million, a cost that the MoD is well aware of as it seeks to develop Fire Shadow.

‘We need to get Fire Shadow’s price to around that, which is a big challenge,’ said an industry source.

40 Afghan Militants Killed In Battle With Nato Troops

KABUL, Afghanistan (CNN) -- Two separate battles that militants fought with Afghan and NATO troops in southern Afghanistan over the weekend left at least 100 insurgents dead, authorities said Sunday.

In the first incident, Afghan authorities called in NATO support after they spotted insurgents gathering on the outskirts of Laskhar Gah, the capital of Helmand province, late Saturday night.

NATO troops bombed the gathering that was planning to launch mortar attacks on an Afghan army compound, according to a statement from the International Security Assistance Force.

The force is an alliance of about 40 nations charged with supporting the Afghan government in maintaining security.

In the second incident, 46 militants were killed during a three-day operation that began Thursday in the Nad Ali district, also in Helmand.

No Afghan or NATO soldiers died during the operations, said Assadullah Shirzad, the province's police chief.

Helmand is an important front in the war against Islamic militants. It is considered the world's largest opium poppy growing region, and that trade has helped fund insurgent activities.
