Pfft, the F/O got an exciting ride, and learned a lot at somebody else's expense - he doesn't have a tiller, and he couldn't exactly stand on the brakes while they're backing up - all he needed to do to cover his butt beforehand was say, 'Hey Captain, that's a really dumb idea and I recommend you have a rethink!' then sit back and watch the show - awesome! Being an F/O has it's perks you know, you should milk them for all they're worth
Here's my rule of thumb though for reversing the -200: NEVER DO IT. I know the manual says you can.....but just don't.
