Peaches' other thread got me thinking about this. I've seen several aircraft that could back up on their own and been on a few too. If you've ever flown on an MD-80 there is a strong chance that you've backed away from the gate under your own power. I've seen the Blue Angels support C-130 back up under its own power, and when I was watching Discovery Wings yesterday I saw the C-17 land, stop, back up, and turn around in about a 1500 foot space. That's pretty impressive for a plane that weighs over 250K pounds. Also got to see video of the C-130 that had been modified for the Iran Hostages rescue mission. It had about 8 sets of JATO rockets at various points around the fuselage because it was designed to land WITHIN a sports stadium and take off again. There is some video of a prototype (crashing) using this system at: http://www.theaviationzone.com/media/c130_credible_sport.mpg But I also saw some shots on Wings of another C-130 taking off using this system and they were airborne in about 100-150 feet. ;P Ahhh... just found some details (don't you just love google?) http://www.spectrumwd.com/c130/articles/Credible_Sport.htm Here's a shot of it taking off: Close up shot of some of the rockets near the front: I'd like to know what the rate of climb was.
