Hello... i am absolute beginner in skydiving. I only made a few tandem jumps... id like to do an education now jump for myself but i have a problem... the pressure differences are too much for my ears and i can hardly compensate that. The result is i am taking risks on my health (concerning my ears)... besides taht im totally fit and in every aspect qualified for skydiving. As i said i jumped a few times and i loved it, i want to jump on... alone... more often... Now i had the idea of a pressure helmet, well they are there yet.. only beeing done for military issues for very high altitudes concerning the whole body and so... now i would only need a helmet keeping the pressure for my ears and providing me with oxygen during the flight... so only 10 mins or so, going up jumping, landing... thats it. I know how im saying this now it sounds like this is the easiest thing in the world... but i realize that im not a professional... no far away from it, but i wanted to know if you ppl think this is possible... having only a helmet taking care of the pressure in the head and keeping the pressure from the ground for about 10-15 mins. So i thought i get me this helmet... put it on on the ground shortly before a start. Put on the oxygen flow, the pressure is like on the ground... going up... still same pressure... jumping, landing... again on the same level as i started i take of the helmet and its cool. I thought this could work as the pressure differences are actually not that high... i also jumped without these things (it will hurt my health if i do it regulary), so it wouldnt need be a NASA approved helmet, as it only would have to work until 4000-5000m... Well thats the idea i had... and i would kick my ass if cant say i tried everything. Lets take aside the money aspect... would it be possible without wearing a space suit or sth like that... Would be glad to hear some opinions...
