This was my first tandem jump done with SkyDive Philadelphia at their Perkasie location. I did not quite know what to expect, and I have a massive fear of heights, so the jump was a big step for me. Lucky for me, I got Pete S. as my instructor, and he was incredibly reassuring. He immediately instilled trust and a feeling of being safe. He talked to me all the way up, explained what to expect, and it was exactly what I needed. Even when we were at the edge of the plane ready to fall into the airy void, I felt sure that nothing wrong could happen to me. And that made the jump amazing. The calm that you get to experience after the parachute opens and you soar above all things earthly - nothing comes close to that. It's been three days since I first jumped, and I am itching to do it again.
