This is a procedure
that use to be common place awhile ago. Don't forget you can still
use it subject to company and airport restrictions.
I use it all the time, blinding bit of fun and can get you out of
those awkward corners.
The key to it is to roll forward a little first then go into reverse
thrust. Trying to do it from a standing start you will blow the terminal
Once it's moving backward ease off on the power but making sure it
still in reverse thrust.
Don't stamp on the brakes to hard either. If you are light just going
to forward thrust will stop you smoothly.
Must have somebody to Marshall you though. Hand signals are confusing
