Maybe my choice of words was wrong - they said they were listing.
I also saw the segment of Dan Schlund - who calls himself "Rocketman" (now there is a coincidence) on Close up. He flies the only active bell rocketbelt in the world - maximum flight time 30 secs, fuel cost about $2000 per flight, and its so hard to fly the rocketbelt as he said "more people have walked on the moon than flown one". The Martin Jetpack is not like the rocket belt, it is better compared to small personal helicopters.
