I logged into Main Arena and were checking roster and setting up setup, after minute I saw Spitfire taking off, but not like normally.
He was having big flames coming out of his plane while rolling up to the skies and still in the air.
I don't know what that was, but never seen such flames and definetly not on planes that just takes off - which immediatly reminded me of the Concorde.
It looked very odd when flames were raising upwards and leaning sometimes backwards a bit.
But this guy never wen't down and flaming quit shortly after I stumbled the screenshot.
(Rocket assisted take-off in a spitfire?)
