And you believe everything you hear on TV?
No I misunderstood the narrator's explanation about the parachutes being trapped. To correct my post he actually said "Inside the parachutes' container the cords are snagged. They trap the main chute and the reserve. There was no chance of either of them ever deploying properly".
I thought they were "trapped" before he even jumped.
But if I understand correctly, he pulled the ripcord for the main parachute and it snagged which caused it to fail to open properly and also impossible to cut away completely. And when this happens the reserve will tangle with the main.
Sorry, should have put this under General Skydiving Questions.
