Jumping without a parachute is a bad idea.
Literally and metaphorically.
It’s a risk that has zero pay off.
Unless, perhaps, you have a big enough net to catch you.
Today I came across an outstanding video of Luke Aikens who attempted a 25,000 ft skydive without a parachute. He’s in free fall for about 2 minutes before a massive net breaks his fall. The video is well worth a watch—especially the final moments where he is lining up his path of descent with the net.
