Bob Gullickson's kind-of wheelchair resembles a high-tech go-cart more than a wheelchair, but both Gullickson and inventor Ky Michaelson agree that a standard wheelchair isn't safe for that kind of speed.
I can't find any info about him except this and his obit. If he ever did get this on the dragstrip, there isn't any mention of that escapade on the internet. His facebook account is closed.
In 2001 he entered the National Veteran's Wheelchair Games traveling to New York City and earning 2 gold, 1 silver and 2 bronze medals.
