Yes, they will flick you out
No, up and in. the flow goes from the bottom to the top.
Yes, I will grant you that, I phrased it poorly. I should have said it will spit him out of formation.
Suck you in, chew you up & spit you out, more like. It seems to me they are staying above the wing and engine centre line; no doubt to stay in as calmer air as possible. I wonder if they practiced with smaller prop a/c, moving onto smaller jets and then this extravaganza. There ain't no simulators. Perhaps somewhere there is a more detailed documentary of the R&D of the jet pack. I remember the 1st experiments made with rockets; but they had little thrust control. Light the blue touch paper and enjoy the ride. If these are jets I assume there is some kind of thrust lever. Next question is what will the military think of it. Usually, when they get their hands on something, it whizzes along its development path.
