Not model airplane stuff but worth looking at.

What a truly unique masterpiece in art and aviation... Thank you Keith for sharing it.

I really enjoyed watching that Keith.

That is COOL!
Love it!
What is the case that the pilots carry with them to the cockpit?
What do the chase cars do during landing?
And, can you see stars once you get that high? All the pics I see the sky is just black and there are no stars??

Nitrogen/oxygen source for the suit. The main body of the suit is filled with nitrogen, there is an air dam around the neck, above that in the helmet is pure oxygen You don't want to breath regular air, because you would get the bends. Same with all the astronauts before the shuttle (which operated with sea level pressure air, costing them tremendous weight but was compatible with Soyuz/Mir/ISS and requiring no special pre-breathing - except for space walks since there is no way to make a soft suit that runs on 15 psi air).
The chase cars call out the altitudes, since the U-2 is one of the most difficult of all airplanes to land. It gets in ground effect and just floats, even with everything hung out to create extra drag. Also, gives the pilot group a reason to buy the latest hot rod cars on government money, so it will be fast enough and accelerate fast enough to catch it after it passes.
Probably. The issue with this (and the fact that you also can't see stars in pictures from the moon) is that with the earth in the FOV, the exposure settings are set for that, which makes the stars far too faint to be recorded. Same reason you cannot see stars in the daytime, your pupils contract to handle the sunlight and ground reflections, they expand at night to improve night vision, also passing enough light to see stars. Film in particular has a rather narrow range of acceptable exposures, 7-8 "stops" or less, same with digital, that is about a factor of 512. The even a bright star is about 25 billion times less bright than the Sun.

Back in the early '70's I watched a lot of U-2 landings in Australia. One of the chase cars was a truck with 2 guys sitting in the back. When the U-2 slowed to a fast running pace the 2 guys would jump out of the truck carrying the two pogo sticks needed to hold the wing tips off the ground. It was comical to watch but necessary :).

Had to reboot computer twice trying to down load the link. D>K

Wonderful photos / art and story .... thanks for posting Keith.
Wasn't Larry Driskill (a combat guy) a U2 driver?

Thank you for the info! Yes I too would buy the latest hot rod for chase cars.

Runs in the family. The SR-71 start carts used up all the Buick 401 wildcat engines....

My brother got to do a ride along in the U2 spotting car with a U2 pilot - at Beale I think - . I guess they take turns spotting for each other. Not a documentary, but a ridiculously close view.
Theres a few other videos he shot if interested. Of course, there is the video of his younger daughter solving a rubics cube while riding a unicycle, but that's for another day.
