That link rocks.
I just got an email update from this guy tonight, here is what he had to say about the test he had planed. lol
I tried to test the jet pack today and had trouble with the propane gas getting to the engines. So, I was unable to start the engines today. This combined with the bad weather here in Ohio has slowed things down, and is making things a little more difficult for me. This was the first attempt to start the engines with the large propane tank and regulator that I have assembled for the pack. These setbacks are to be expected with a project like this. I will continue to keep you informed of my progress in future e-mail.

I love the -This was my first attempt to start the engines - Maybe this would have been good to try before you claimed it would fly....
