Photo suggests Jet2 parked on stand 24 and Ryanair behind it, possibly taxiing towards stand 22 (Ryanair seems to be EI-SEV that arrived from STN at the right sort of time according to FR24). The photo puts Ryanair either on the Alpha taxiway - in which case it should not have hit anything - or on the north edge of the main apron where there is insufficient clearance to taxi behind stand 24 when it is occupied despite their being marks on the ground.
