Hi Tower Ranger
You are quite correct, it was sitting on stand 23A this morning attached to a tow bar getting ready to fly down to Dublin.
So many aircraft on the apron these days it is sometimes hard to see the wood from the trees especially from a mile away.
It then uncoupled as news got out that a deranged EGAC Ramper was seen leaving Belfast, heading towards the countryside in a luggage truck threatening to ' Scoot' across the long and very smooth runway at BFS in between the never ending stream of orange tailed arrivals and departures!
Cheers WA
