    Very good Markus,
    Great,
    
    I've been looking for a wing section diagram to locate the tires
    in the wing. Just ahead of the main spar. This wing has two and
    the trailing spar for the elevons to hang off of. The rest are
    formers. The main spar, leading edge and the fuselage form a
    triangle. But the tires are in harms way in this case
    considering the military photo. I'm guessing still that one or
    both of the tires exploded. I know they are filled with nitrogen
    which is inert-but does anyone know the properties of nitrogen
    when it's heated substantially. In any event they are
    pressurized to about 300PSI at SL. That's a lot of pressure in a
    near vacuum.
