As for the fella saying that his flight needed reverse thrust in order to stop during the taxi! You don't know what you are talking about.You obviously have absolutely no idea so why comment on something when you are clearly not in the position to do so? Anyone that has taxied a -200 will tell you how effective the wheel brakes are.I must admit I have only taxied empty aircraft but let me tell you that if you operate the brakes with anything more than a gentle push with the toes then the thing will stop immediatly.Just how effective do you think reverse thrust would be at a ground speed of 20-30 knots with the engine at idle?
Could it not have been that the crew were cycling the reverser on the taxi-in to check an inication fault or something?

Oh, God, I'm so sorry. I merely asked a polite question, which you finally got around to answering at the end (yes, this sounds plausible), after burying me in the previous paragraph.
