They only have a flight time of about two minutes. It appears longer because they stitch together clips strategically. Edit: It appears that I confused Vince Reffet with another "jetpack guy" - Richard Browning. The number was for Browning's device. But although you could get more airtime by adding wings, the overall point still stands - the flights are relatively short.
