escape spoiler
extended (usually from doors) from transport aircraft to
enable passengers and crew to evacuate quickly in emergency.
(Possible confusion with escape chute.)
escape spoiler Aerodynamic baffle extended upstream
of crew escape door or chute.
escape tower Connects escape rocket(s) to vehicle;
separated if ascent is normal.
escape velocity Speed body must attain to escape from
gravitational field. Earth 25,022 mph, 11.186 kms –1 ,
36,700 ft/s, Moon 7,800 ft/s, Mars 16,700 ft/s and Jupiter
197,000 ft/s.
