leaf blower propulsion system

[PStechPaul]

I think that works like thrust reversers, where the blower air blows back from the umbrella to give forward thrust. It would probably work better without the umbrella and by aiming the blower to the rear.

This Florida man zips around town by aiming a leaf blower at the umbrella he is holding. https://abcnews.go.com/US/video/flor...hicle-73659512

Can thls be a good idea? If so, should we turn the jets on a 787 to face forward, blowing on parachutes.
