Don't know what happened but it's bad

I'm a bit surprised at those who are talking about hitting the brakes anyway. If you have a front tire go down, the last thing you want to do is hit the brakes. Hitting the brakes would likely yank the wheel out of your hand. My brother had a front tire blow out in my CAR, after gaining control, he just lightly applied the brakes. That immediately put the car into the guard rail. And that was only a car. Think of what that would do in a coach.
