22 d in each box beam 20 the engines 22 are preferably constituted by both rotating and counter rotating properties preferably there will be an even number of engines 22 and there will be an equal number of rotating and counter rotating engines 22 to balance the device all engines 22 on one box beam 20 a may rotate in one direction and all the engines on the other box beam 20 b may rotate in the other direction however this is just one of many options engines 22 on one box beam 20 may be both rotational an counter rotational further the engines 22 may be of different power and thrust and not all of the same power and thrust it is desirable however that whatever the selection of engine types and positions thereof the sum of engine force rotating in one direction preferably is substantially equal to the sum of engines force rotating in the other or counter direction fig2 of the drawings shows a side view of a harness 10 with a mounted support arm 16 as generally represented in fig1 of the drawings in this figure a pilot 38 is shown wearing the harness 10 and frame.
