Hmm, so the QF crew got criticised for leaving the pax onboard too long with a potential hazard to the pax outside (fuel leak, running engine etc)
Then the EK crew get criticised for NOT keeping them onboard with a potential hazard to the pax outside (hot brakes etc)
Case of can't win no matter what????
The pictures I saw of the pax deplaning, were doing so after the tyres had deflated... IMHO better to get them off in a relatively controlled manner than to keep them onboard in a state of panic and risk things going pear shaped (we all know that 'some' EK pax are not that great at following instructions on basic things like seatbelts) so why would they do what they're told if they think something is wrong outside?
