Dont forget the media love to hype things up. Jet2 have never caused the EMA runway to be closed at all.
The Jet2 earlier in the year only blocked the runway for 10 minutes whilst they confirmed the u/c hadnt overheated and tyres hadn't deflated then the aircraft was towed off
And then last night wasn't even on the runway. They made it to stand before evacuating but I guess RFFS were possibly committed to the evacuation and couldn't provide cover for runway movements.
