You will find that this will RAISE your heart rate just slightly. LOL.
I remember as we boarded the litte cessna in small groups and taxid out and took off the ole ticker starts to thumpity thump a little harder and your mind starts to play tricks on you . (example given.....you idiot this is a perfectly good aeroplane...why would you want to jump out it?)
My feet felt like lead when it was my turn to step out onto the wing spar and prepare to launch myself.
Its a thrill even if you only do it once.
