Damaged aircraft is not going to happen soon
And other things are there in the to do list.
So i asked about that in Google play, and the answering bot said it will be part of a new Handling system, is it in the update that came out? Oh and maybe you can turn on/off emergencies (if you want it or not) And during the emergency no planes come to your airport so there is no que, for that they could add the third runway in IAD etc
No, there are no emergencies in the game and many times the devs have said no to this due to using real life airlines in the game.
There maybe maintenance issues that come in future updates causing delays on stands and stuff and maybe things like fire trucks etc. in the background but actual emergencies are almost never going to happen
