  1. A tow airplane pulls it up ✔
  2. It runs its own engine to climb
  3. It jumps off a tall tower

Why: A pure glider has no engine to climb from the runway. A powered tow airplane commonly pulls it aloft before releasing the tow rope.

Huh, didn't know that: A winch launch is another way some gliders reach flying speed and altitude.

The dad joke
The glider asked for a lift, and the towplane took it literally.
