Engineers Taxiing Aircraft
I've just been reading the Pushback thread. My question is not strictly about pushback, so I'll start a new thread.
At JFK, and possibly some other airports aircraft were not allowed to be towed on taxiways at peak times as their slow speed would have caused congestion. I don't know whether this is still the case or whether towbarless tugs now make towing permissible.
I understand that aircraft for some airlines (I think that BA was one) were taxied under power by engineers rather than flight crew. Does anyone know if this happened much and if so how much training did the engineers require. I suppose that you need the same ATC training but that you can do rather more damage when powered by two (or even four) RB211s than a Detroit diesel.
