The urge was obviously to evacuate immediately. If both engines were running, it does cause a nasty red spray coming out of the back, and the ones pouring out of the rear door getting singed and blown off their feet. Quite possible the pilots were unaware as they had possibly turned the aircon packs on after start. Definitely a time to sit tight and wait for the word! Don't you just hate it when babes in arms either get sucked into the engine or blown out of mum's arms?
