For the next update..
I think we should have sonic booms. when a certain aircraft (or any vehicle) reaches supersonic, i think it would be pretty nice to have a sonic boom. It adds a more realistic feel for the game.
and snorkels for engines
exaust just like inlets their should be exaust from engines and their should be a diesel option for engines so when use pitch for example their should be a cloud of black smoke and you should be able to adjust how much smoke their is.
YES PLEASE DO
