Testimonials
Today, I went skydiving with my friend and mother. My instructor Jarred was so nice and friendly, as well as, my videographer Mike! They did a great job and made sure I knew what I was doing. It was just a great experience!

Ted and Crew (Corn, Woody, Barry, & Kristin), Thank you for providing one of my best Father’s Day I have ever had. It took a long time to make this dream come true. Two years ago I weighed in at 426 pounds. On August 11, 2010 I had a Gastric Bypass Operation. I have lost over 200 pounds since then. Along the way I also had two knee replacement surgeries in 2011. I know I can speak for my jumping partner Crystal and I about how impressed we were with your professionalism and dedication to providing a safe and entertaining environment. We both see why you all love your jobs; although I’m not sure I would consider it work seeing how the passion for what you do shows through. Our short time at the hanger made us feel as though we were part of the group. Even our supporters got something out of the experience. Even though I do not show much emotion on the outside, I had a ball. I especially like leaving the plane in a backward roll out, it really looks cool on the video and in the pictures. For me this life experience comes in at number 3, number 1 was the birth of my daughter, number 2 was my becoming a United States Marine. Once again thank you for a wonderful experience, “We Will Be Back.” Jim Reece
