Oh, and incidentally, that is a barrel roll.
An aileron roll does not keep positive G
A barrel roll can be anywhere from a loop 1 degree from the vertical to just far enough off an aileron role to maintain positive G,
Role and pull equals barrel
Roll equals aileron
If you fly a helical path describing the inside of a tube, then you are flying a barrel roll.
Duh.
