For those of you paying attention, this is a brief lesson in what no to do.

Low hook turn, bad. Broken ankle, bad. Teaching yourself to swoop, bad.

Two malfunctions — line twists and a line over — followed by a cutaway and a downwind landing puts the "fun" in malfunction, especially for your first cutaway! This skydiver was admittedly a little scared since he'd never experienced a cutaway before, so he tried to fix the malfunction(s) while keeping a close eye on his altitude. He managed to kick out of the line twists, but couldn't clear the line over and he cutaway at his decision altitude.

As two skydivers close the gap between each other, one of the jumpers has a premature opening while sit flying. Fortunately they were both on level and nobody was above the opening canopy.

Luckily for Jay, he has cat-like reflexes and was able to grab his helmet before it flew off his head. The helmet was definitely fastened when they exited the plane — maybe the buckle got pinched between his body and the riser, which disconnected the buckle? Has anyone else ever had this happen to them in freefall?

We've seen our fair share of "close calls," but it really doesn't get much closer than a collision in freefall and getting wrapped up in a parachute on a BASE jump. Whoa! #SweatyPalms

WTF? Why? Just.... why?! How many line twists did you count?

An angle jump turns into a zoo dive with a very close call collision. One of the jumpers gets too far ahead (and high) of the group, so he decides to turn around and track towards the group in the opposite direction.

This is the type of stuff that causes fatalities! Not cool.

Ouch, I think I hurt myself just watching this, but luckily nobody was actually injured from this hard opening. The slider comes down the lines like a guillotine on opening, causing a very snappy opening. #InstaCanopy

WOW, this scary malfunction will get your palms sweating! It starts off with a tension knot on the main canopy, which turns into a spinning malfunction. He tries to cutaway, but the cutaway cable was stuck, so he deployed his reserve because he was losing altitude quickly. The reserve opened with line twists, and both canopies went into a downplane. Luckily he was able to cutaway the main once he was under his reserve, cleared the reserve line twists by 500-ish feet and landed safely. Phew!

After inspecting the gear, they're still not sure what caused the cutaway cable to get stuck — maybe the cable housing was really dirty and lodged the cable from coming out?
