jet performance is highly dependent on ambient pressure/flow at the inlet.
During descent this is reduced, unless he has inlet scoops which realign
themselves to the direction of travel.

Bob,
I don't know where the 250HP each engine comes from.
I'll post this analysis again:
Jet engines aren't usually quoted as being of a certain horsepower.
It seems likely the device has 4 x 40 Kg(392N) THRUST engines

THRUST engines (if it has a single engine out
capability this would be about right. One
Claimed 4 engines at 250hp each. just not possible from jets of that
size
possibly 250 N thrust from each.
claims to be looking at 2 miles.. I don't believe it he couldn't
carry enough fuel.
