He is about at 100 feet, which is nothing in a fighter plane. (Wing Span: 12.30 m and it is about 3ish wingspans from the ground in the other posted video)

On a related note, the biggest bird that ever flew was Argentavis magnificens, an ancestor of the Giant Condor. Impressive picture of replica here.

>> Discovered decades ago and formally described in 1980, Argentavis magnificens is the largest bird known. It lived six million years ago during the Miocene period throughout Argentina. It is nearly the size of a Cessna 152 light aircraft, with a 23-foot (7-meter) wing span and weighing approximately 150-pounds (70-kilograms).

It would have been impossible to take off from a standing start. The bird probably used some of the same techniques used by modern-day hang-glider pilots such as running on sloping ground to get thrust or energy, or running with a headwind.
But once it was on a thermal, it could easily rise up a mile or two without any flapping of its wings -- a free ride, just circling. Then at the top, the bird could simply glide to the next thermal and in this way it could certainly travel 200 miles a day -ScienceBlogs excerpts

edit: And the biggest creature that ever flew was a Quetzalcoatlus.

>>A pterodactyloid pterosaur. More recent estimates based on greater knowledge of azhdarchid proportions place its wingspan at 10-11 meters (33-36 ft). However, similar claims to an upper size limit for flight accompanied the discovery of large (up to 9 m (30 ft)) Pteranodon, and azhdarchids larger than Quetzalcoatlus with wingspans 12 meters or more (such as Hatzegopteryx) have been discovered.
A 2002 study suggested a body mass of 90–120 kilograms (200–260 lb) for Quetzalcoatlus, considerably lower than most other recent estimates.[7] Higher estimates tend toward 200–250 kilograms (440–550 lb). -wiki excerpts

I agree with Engels and cybrbeast... It looks like a very well calculated and practiced maneuver. Not an almost-crash.

Low flying planes experience something called the Ground Effect (http://en.wikipedia.org/wiki/Ground_effect_in_aircraft) which basically means that when an aircraft is an altitude roughly the same as it's wing-span, the lift generated by the wings is increased. It's a well known aviation effect.

Thank you for a generally more reasoned post. However, there are a few things I need to clarify before I deal with your subsequent points:

Regarding the size difference between a Boeing 707 and a Boeing 767, there is no need to simply take my word for it:

707-320B:

Dimensions: Wing span 44.42m (145ft 9in), length 46.61m (152ft 11in), height 12.93m (42ft 5in). Wing area 283m2 (3050sq ft).

Weight: Empty 66,406kg (146,400lb)

767-200:

Dimensions: Wing span 47.57m (156ft 1in), length 48.51m (159ft 2in), height 15.85m (52ft 0in). Wing area 283.3m2 (3050sq ft).

Weight: Empty with JT9Ds 74,752kg (164,800lb)

In order to sufficiently contribute to a global collapse, the jet-fuel itself simply didn't need to burn for long enough to significantly affect the structural steel; it was merely required to serve as the accelerant for the fires. Once the fires had taken hold, there was plenty of other fuel (office contents, etc.) in the buildings to sustain them.

Sports Illustrated:

"She's an ideal player," Jackson says. "She has a 70-inch wing span from finger tip to finger tip and she jumps. She always works hard and challenges herself. She is very agile. What's really amazing is that when she is double- and triple-teamed, she stays very mentally calm and still is productive. She is a very confident young lady -- a real joy to coach."

Last summer, while playing for the AAU Houston Hotshots, Griner dunked for the first time, and last month she threw one down. "The whole crowd just jumped up and was screaming," Griner says.
