Skydiving without a parachute

I had no idea that skydiving without a parachute  was possible, and thought this video was clickbait when I first saw its title. Turns out it is possible, and some people are fearless enough to try it. Skydiving sans parachute is possible when one person free falls for a while, and then gets caught by another skydiver who attaches a parachute to them mid-air. Watching this gave me the jitters! Don't try this at home, kids.
