If I pushed an albatross down a well and attached a crab to it to harrass it on the way down it would also fall, despite being a fantastic winged flier.

Imagine them with wings ill suited to vertical flight and hovering, but very fast in the sky while soaring, and with the endurance to keep going for hours.

It’s my headcannon, but I give Gandalf points for forcing the fighter jet into a helicopter arena.
