I suggest that the plane should have names and not just code or numbers
Something like "P-47-D28" shouldn't be allowed but something like "P-47-D28 Thunderbolt" or simply "P-47 Thunderbolt" should be ok
I-15 "Chaika", I-16 "Ishak", Me-262 "Schwalbe", Fw-200 "Condor", P-40 "Tomahawk", A6M "Zero", J7W "Shinden", come on guys be a little more creative than just numbers and letters
Since it would be easier to remember and sort the names rather than some random numbers
