Good information from all contributers thank you Tal, Victor and Arnon
I just finished 25 minuets flight at Sharona ( Thursday 10 am) and used one Item from Arnon's lecture. It appears that by tightening up the two leg straps to his recommendation ( space sufficient enough to slide your hand in between straps and thigh) I didn't have to wiggle into my chair in flight for the first time in month. Very simple, and I am sure that we all heard it before but it took this freshening
up to make it "click" for me
see you all next flight
