"I heard it was something to do with an Atlantic Airlines L188 Electra coming in with 3 (yes 3!!) engines shut down!!
Not confirmed though, just what I heard."
Not sure about this as I was on the Alpha stands when the Electra taxied past and it had more than one engine running at the time...even my top of the range ear defenders are no match for that old beast
It was turned around pretty quickly and off again with Royal Mail on board. Would have thought after a full emergency that it would have had a few spanners look at it prior to despatch.
