DA Aquamaster:I remember a dive book from the 1970's sporting a picture of a very nice looking girl wearing a 50 cu ft sized cylinder of liquid air with a heat exhanger along the side.
Freeflow's got to be nasty.

ScottB:It's what they flew the jet packs with for the 80 something olympics... Which was a toy that got me wishing I could fly.. too bad it could only sustain short flights (less than a minute)..
Take care,

Mythbusters tried it (twin ducted engines) and failed. No-go on the "practical" personal flying packs at this point. Anything that says otherwise is a myth. ;-) (until you see flight footage or see an actual flight, and a cost list)DA Aquamaster:The jet pack, unlike the mini-rebreather, really works. However the fuel supply is very limited with about 60 seconds of fuel on board. They made some cool appearences (flying into a stadium, etc) and did some cool tv and movie scenes with them, but they were all done by combining footage from several 40-50 second flights. Running out of fuel a hundred feet up would be a very nasty situation to be in and would most likely not be surviveable. So watching the fuel guage would have been a critical issue.
A concept that is slightly more practical is a back mounted helicopter pack with two counter rotating ducted fan engines - although the term "slightly more practical" in this sense is still very minimal.
