Tim Pickens uses an asphalt-nitrous combination for both his rocket bike, and his rocket truck. Earlier, he had an igniter failure on the rocket bike. Just a few minutes ago, he was demonstrating the rocket truck (it's in the bed of his Chevy, pointing--no surprise--backwards). He has it chocked for a static engine firing--for some strange reason, he can't get insurance to actually propel it. This time, the igniter ignited, but there didn't seem to be any oxidizer flow. It may be a failure of a temperature sensor that allows the valve to open.

So he's 0 for 2 today.
