Just finished an hour long flight, am getting the ghost formations as well, they disappear when you get close and then reapper behind you, the formation of Stukas with their escort was the only other aircraft spotted apart from a lone Spit flown by another player.
Lost sound at the exact same time that a message appeared saying "Wellington formation spotted in D20". Didnt acually lose sound it became more an intermitent stutter that seemed diectly related to the amount of throttle applied. On the bright side my fps averaged at 42fps which is about the best I've had online.
PS, Flashman AAA was working fine, really noticable over Dover
Anyway was great fun, keep up the good work.
