What happened?

What if the heat shield did not get out of the way and the craft got within 4m from it, triggering the radar to say "4m altitude, turn off the thrusters" ? Aerodynamics - get some. The "software" solution would have to consider vertical descent speed "do not turn off thrusters if vertical speed is greater than 4km/h no matter what altitude you're at". So the shield obstructig radar would not have caused thrusters to turn off. But as long as hield was in the way, it would have to use IMU to deduct its vertical speed and be flying bnlind. Where do you think the craft gets its vertical descent speed from? IMUs can only measure accelerations. -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson |
