Looked again, and you are right Larryleghumper, he didn't release the jack. The block used to extend the jack slipped, it slipped because he got in a hurry and didn't place it correctly. Damn near got that one guys fingers. Sorry, that is not hating on Rubs, it is pointing out rookie pit crew mistakes. I've been racing and pitting in Baja for over 40 years, I believe I'm qualified to critique a pit stop. Dropping the back of the car to the ground is a big deal. The chant of a good pit crew is "Slower is faster" takes twice as long to recover from a mistake made while in a hurry than to slow down and get it right the first time.
"I couldn't wait for success, so I went ahead without it."
