IMO, the variable rate of synchronized fire is an important step forward. I've been waiting years for somebody--anybody--to implement it. Good show!
Next, or eventually, need to implement engine stoppage as a result of holed pressurized fuel tanks, rather than have planes fly on and on and on until the fuel finally drains out. For planes with reserve and/or gravity tanks, implement the ability to switch tanks.
Also, any plans for in-cockpit damage?
Again, fantastic work. Looking forward to it very much.
