Could the way an owl captures its prey point to coaster elements?
"Other species prefer to soar, or make quartering flights, scanning the ground below for a suitable meal. When a target is located, the Owl will fly towards it, keeping its head in line with it until the last moment. This is when the Owl pulls its head back, and thrusts its feet forward with the talons spread wide - two pointing backwards and two forwards.
The force of the impact is usually enough to stun the prey, which is then dispatched with a snap of the beak.
Owls can adapt their hunting techniques depending on the type of prey. Insects and small birds may be snatched in mid air, sometimes after being flushed from the cover of trees or bushes by the Owl. Owls that catch fish may skim over water, snatching fish on the fly"

Soaring, being snatched mid air, brushing with trees(AE?), high height
"impact" dives all sound fun to me.
