Something I want to do (to one of my longtime online flight buddies) is to play follow the leader under bridges, with him following close.... and drop a couple bombs from my Se5a as I pass beneath the bridge.... if I time it right, he'll either:
1.) Fly through a pair of water geysers, which would be "ok", or, if I'm lucky,
2.) Be slammed upward by the concussion into the bottom of the bridge, without warning
I owe him some major payback for many years of online practical jokes.... this would be classic.
