When someone jumps into a cave and lands at the bottom with a parachute...what's next? How do they get out?

I would guess they are also rock climbers.

The cameramen have ropes? Seriously, not being facetious, maybe they only do it with support persons who stay topside with extraction gear.

Side door at the bottom. Most likely whatever carved out the cave had to find an exit so there should be another way out.

… a lobster, a match and 7 sticks of dynamite.

Or climbing gear.

There was a movie where they jumped into a huge cave and then they climbed out with rock climbing gear.

Nonchalant? I’d say those people better start getting real chalant about that.

they might have ropes with them..
