 “Though my body is warm inside the nylon suit I start to shiver and wonder if what we’re doing is right,” Potter wrote. “Wingsuit BASE-jumping feels safe to me but 25 wingsuit-fliers have lost their lives, this year alone. There must be some flaw in our system, a lethal secret beyond my comprehension.” 
 
 Strange acknowledged the dangers of wingsuit BASE jumping on his social media accounts and mourned the deaths of fellow jumpers. 
 
 After Potter died, Strange wrote, “You were one of my favorite BASE jumpers and getting to fly Wingsuits with you off Via F the next year made me beyond proud to know I had gotten to BASE jump with someone who I regarded as a legend. Thanks for your Wingsuit advice, I'm sorry to hear you died flying. See you on the other side.” 
 
 At 17, Strange became the youngest person to climb the world’s highest mountains in seven continents, known as the “seven summits.”
