The USAF has made much of the fact that the C-17 can back itself up using reverse thrust. I have a couple of questions about this capability for those who work with this aircraft and thanks in advance for your help.
1) In practical terms, is this feature used often, occasionally or at all?
2) If so, does it create alot of flying debris or is the blast deflected away?
3) Is it used in a congested ramp environment?
