NBC had some nice video tonight. There is sort of a pickup truck driving in front of the regional jet.
we all know that there are LOTS of things going on at an airport...tugs pulling baggage carts, pickup trucks, boxes blowing along the taxiway...a myriad of things.
Some nice animation showing how much A380 wing hangs over the standard 75 foot wide taxiway.
The truth is that this plane requi res multiple taxiways (clear) to get where its going.
I don't think ATC will ever take responsibility for wingtip clearance of one plane with another.
