I landed on 24R after the incident. For what it's worth, the 73 looked to be short of T1, but who can tell for sure except those actually on the scene? Perspective / angles etc. Thank goodness there were no injuries that we know of. Danny's diagram looks to be almost spot on.
Let's just wait and see what the inquiry brings.
If it's a bus though, it hardly raises an eyebrow in the press, even though there were injuries (allegedly.....):
From May 1998:
"A bus ferrying passengers between a plane and Terminal Two collided with a plane, injuring several passengers. The wing of the Onur Air MD88 broke the windscreen of the bus, missing the driver's head by inches. Airport authorities the didn't know how the accident had happened, and said an inquiry into the incident will be launched. Thank goodness the accident was only minor - the injured passengers, taken to Wythenshawe Hospital, were only slightly hurt."
