 Fire, all kinds of things. The people that were on the plane, one of them said that everything was good. We start down the runway full force. All of a sudden, it felt like we were on a gravel road. Then it felt like we hit a big pothole in the road. Well, the pilot recognized something was wrong. He powered it back down, safely maneuvered it over onto one of the side taxiways there. Fire crews go rushing out to go put out the fire that actually started from this tire. I mentioned rough week.
