"Written off due to severe damage" Is infuriating in a bomber

As if playing bombers wasn’t hard, whatever does the calculation in this game is insanely broken, I end the game as a shackleton with 5 kills, my hull is extremely damaged, one flap ripped off, ALL ENGINES ARE WORKING with not even a leak, tail is controllabe, control surfaces undamaged, I would easily make it to base and land, but no. WRITTEN OFF DUE TO SEVERE DAMAGE, and now i got a death on my stats and have to pay repair. this is beyond cheap.
