Two hours ago, the shuttle landed in California. Here in Sweden I heard
on the radio some very interesting data. They said that when the vehicle
approched the coast of California, its speed was about 4 Mach. Later it
was mentioned that the shuttle's speed when it came in for landing was 2
Mach. Is this really so? Does anyone know how fast Discovery were travelling
at the moment of touchdown? Surely it must have been lower than the speed
of sound, or?? Finally: does the spaceshuttle have any means to decrease its 
velocity with flaps or something alike?
