Ok so when i try to land and i mess up on the landing, the plane always does this:
I hope they add some crashing physics to FSX and after you crash it goes to a screen that lists all the problems that caused you to crash so you can learn from your mistakes and do better from it.
best solution here: Don't mess up on landing.
I agree that not messing up, is the preferred option. Invariably, a crash like that is due to excessive vertical speed. Of course, that assumes down and locked landing gear. FS does provide flight analysis so you can confirm the cause of the crash, but if you want something fancier, you can try FS Passengers. It produces a report that describes your flight.
