As usual, flying is easy, but landing is hard. Someone commented on a previous generation of jetpacks that "knees are terrible landing gear".
What are they using for a turbojet engine? One of the great frustrations of light aircraft is that nobody has been able to make a cheap and reliable jet aircraft engine. It's possible to make one small and light enough, but they don't seem to get any cheaper below 6-passenger bizjet size. NASA put some effort into this in the 1990s, and Williams tried, but all that happened was that bizjets got a bit better.
"It is with unimaginable sadness that we announce the passing of Jetman Pilot, Vincent (Vince) Reffet, who died on the morning of 17 November during training in Dubai."
Mfgr: (via Google Translate) "The CAT JetCat model jet turbines are designed exclusively for model flying and are not suitable for any other purpose. Definitely not for people
or use goods or by any other means, except exclusively for model aircraft,
because any other uses lead to personal injury or death can."
There are low cost (well, US $10,000) jet engines, but they are not human-rated.
