Allthough I have to say, the way the BBC reported it you would have thought the aircraft was trailing smoke for miles and made a very dramatic landing. From what I was told, most of the staff thought it was a normal ferry flight from LHR on its way to BAMC and didnt realise anything was wrong untill they saw the fire service following behind.
I expect it was slightly dramatic from the point of view of those onboard, and the a/c must have been heavy. Those staff that
thought it was a ferry flight are obviously those that needed to know nothing of the incident. ATC would have initiated the emergency which involves contacting the Airport Authority so those that
really needed to know did.
