yes. funny & true at the same time. at first I thought, it's some sort of thrust.
as far as I know it's some cold pressured air via powerful fans.
They use same fans to generate downforce to keep it upside down.
It's like seating in a multiple-chopper where blades are ready to be blown any time.
I'm not criticising the product. It's mesmerising & I admire the effort but we have to think of all the risk factors too.
Hope that we've started this journey & we'll get somewhere near flying cars.
