Yeah he had a throttle problem and also he had the
caster WAY out there which can cause the wheels to
flop over when backing up(great for going forwards
but thats what happens when backing up).... as soon
as the front started turning sideways he thought he
could correct it by putting in in drive to straighten
it out BUT then the throttle went open... basically
his whole problem was a throttle issue
EDIT
I seen John Forces FC do the same on the front wheels
when he backed up to fast... some times they get into
the death wobble when backing up, where they start flopping
side to side.. if you have a hold on the steering then
it can break your wrist... you just need to stop

I understand the throttle sticking but how did the car go from reverse backing up to forward and into the wall?

You can tell he was having problems after he came to a stop from doing the burnout.Maybe getting it into reverse. Then, when the front starts to come around you hear the throttle come up, the car goes in forward and he hits the wall...

From the sound of it it was a throttle linkage problem. It hung up when he stopped the burnout, then when He tapped the throttle to back up it went wide open. Probably lost the return spring? He should have hit the fuel shutoff/kill switch the instant he knew there was a throttle problem.
And finally, where are the safety guys with some balls. That car ran over 40 seconds against that wall without an attempt to shut it down. They got there, but slow in my opinion. ANYTIME you see a car crash the safety guys should be instantly running that way with extinguishers.
I have been sideways at speed and seen the safety guys at BIR running towards the guard rail in case I went on my lid. Now that is the kind of reaction I can appreciate! I was glad to be able to wave at the guy as I coasted by!!

The guy was making his license runs. When he was backing up the engine started running away again he reached for the handbrake but grabbed the shifter instead.... from one of the guys who was helping him. Mike

I went to a drag school back in 1992. They taught us to sit in the car bindfolded and use the controls because you can't see them very well with a helment on. Which I did for several hours long before the car was even ready to go. It helped a lot.
There's lot's of things to do in a alky dragster, like letting the clutch out when the lights go yellow, trying to keep the Rs at 5800 during staging, shift twice in 3 seconds and pull the chuts before the finish line like a 1/2 second after putting the car in hi gear. Not to mention steering.

I could do all that bindfolded, swear.

Also I have run stack injected BBC motors like he had. I setup 2 different injectors, one for a BBC and one for big chief pontiac. I bet the linkage was not setup correctly and allowed it to go over center.

A friend of mine ran an old slingshot dragster with a 440 and the short stack fuel injection, on alcohol. If there was the slightest bit of humidity in the air, it would try to ice up the inj linkage after the burn out. Sometimes the throttle blades wouldn't shut completely and be idling at 2500 or more and that just compounded the problem.
Looked like to me that he turned the steering wheel when he put it in reverse. And anyone thats ever been around a old slingshot digger knows that when you're backing up, even slowly, there is almost no weight on the steer axle.
Tough way to learn though. Thankfully, most of us got our experince with out these kinds of results. (and everyone of us was a rookie once)

If you dont hold the steering wheel straight with a
bunch of caster the tires/wheels will flop over( its
like a road grader).. the faster you go in reverse
the more they want to flop sideways
