@flightradar24 It is low fuel. Pilot just did an announcement saying the flow of incoming flights to Manchester was "considerably slowed", we were in a holding pattern then diverted to Newcastle to refuel.
@OSINTMilTracker I am on BY2421, currently sat in Newcastle airport waiting for fuel to head back to Manchester. We were told there was something happening in Manchester Airport which meant we couldn't land. All seems fine on the plane.
@OSINTMilTracker We did see a large emergency crew next to the runway with blue lights going as we landed but they haven't since moved toward the plane.
