Had an LH A343 divert into MAN back in '95 and there was no towbar available for it as back then it was still a fairly new type that didn't operate into MAN, so the a/c had to be parked across 2 remote stands so it could self manouvre out again.
I would have though that the Airport's Ops department would know what equipment was avaliable from the various handling agents to avoid situations like the VS situation occuring.
Also AMS has TBL tugs, so I'm sure that one of those could have been used - we use them at LHR on the A346 just about everyday.
