Engineers were unable to source the part locally in the UK so BGZ declared night-stop and all pax around 70-80 were sent to the hotel.
The same part from BGY was sent on PK701 ISB-MAN today THU which also operates B772-ER however inorder to save time the aircrafts were swapped.
PK721 departed 28hrs late at 1548LT THU 12OCT.
A new part was ordered from Seattle and same will be put on PK702 MAN-ISB if BGZ departs as I've just been told it's returned back to stand after pushing back initially with STD 1530LT

BGZ finally departed as PK702 MAN-ISB just before 1900LT nearly 0330hours late !!
Just as well I'm not at work today !!
