There may, be more to this than meets the eye. The ESIR's are in and no doubt the full truth will come out from the reliable eyewitnesses, including the odd LAME, the airport manager (who did get on the radio) and some aircrew,(ASIC holders and allowed to enter and walk the hardstand when attempting to alert pilots of a hazard) who all saw the whole drama played out, then walked the taxiway and strip after the aircraft had left.
