Being a little hard on him aren't you?
Everything that makes the game harder does not always make it better. Getting back to base with a wounded aircraft is the hard part. Emersion is a great part of making the game fun. Realistic challenges are better than silly ones. Returning to base and landing on the field with a damaged plane, but missing the gray patch of ground by two feet seems more silly than realistic. I think that's why people question it.
You really don;t think there could be an improved version that creates better emerssion and maintains the challenge of a 'successful' landing. Come on, you're the expert/veteran/ guy. You can do better than that. 
Vinkman, you're a smart guy and you know that in programming and in this case in particular, you have to define the boundaries/parameters in which counts as a successful landing. The boundaries must be defined, regardless of whether that boundary is the edge of the concrete, the edge of the base perimeter or whatever, the boundary must be formed. So regardless of what the defined boundary is, there are two sides to that boundary, unsuccessful landing and successful landing.
What better boundary would you prefer there to be instead of the edge of the concrete? <--- Answer this question please.
Or would you prefer there to be a gray area where if you miss the hard boundary it says SYSTEM: Vinkman almost successfully landed 8 kills but he missed the boundary by 2 feet"
