It did have a serious engine fire as far as i know and it was part of a flight of two that went across the pond to a dusty place a few weeks ago but i'm assuming enroute it had the incident and never made it there.
I Don't think it will be repaired at Fairford, i think it might be just staging through and will probably go back to Dyess like it is via a few more airfields on the way (Kef or Lajes?)
Surely with three engines (or will it have just two working) it is now limited to cross the pond the usual way and so will need to hop along via several places on the way?
