It was suspended the year prior.
Experimental plane and ran out of fuel.
Did you know, if you build your own plane, you don’t have to have a license to fly it?
Only if it weighs less than 254 pounds, which puts it in the ultralight category. Otherwise you need at least a sport pilot license (less than 1320 lbs gross) or private pilot license. At the time Denver crashed there was no sport pilot category so he would have needed a current private pilot license.
