I want to remind everybody that fire rescue did just fine. They can clearly be seen on this video, rushing towards the plane while it is still rolling. At 0:17 the airplane comes to a stop. The first firetruck starts dousing the ground before reaching the engine at 1:07 which would amount to 50 sec respond time.

Discussions about taking shortcuts crossing grass I will refer to this:

Fire rescue is heavy equipment. No use getting stuck in unknown territory.
And, why didn't they evacuate? Were they so confident in the aircraft they thought "it worked in Vegas, chill yo"? Another video from the cabin, brand new today!
