If you land on a field you can still drive it to the runway for a successfull landing........... if you cant drive it back to the runway you get a ditch (correctly IMO)
In fact I think a "ditch" is more accurate if you land a plane with prop, gear or engine failed on the runway.
I suppose you could differentiate between the perk/point allocation and the system report re kills.
Instead of "landed" it could be "returned" with "X" kills in a "Y" (plane/vehicle type) (dropping the squad reference which is often lost or half lost at the end of the line.......or abused with silliness)
eg
Goober returned with 4 kills in a 109G10
"Returned" is better english re vehicles anyway.
Several options on which way to go to qualify for a "return"
1) Exit plane/vehicle within a preset distance from tower.
2) Exit plane/vehicle from a runway position.(as now)
3) Exit plane/vehicle/walker from a runway position.
3) allows for mechanic's idea of allowing folk to walk back to base after bailing via chute or from a ditched ac. (for points/perks the flight still only scores as a bail or ditch)
Re fueling.........
I would love to see the re arm pad scrapped and ac re arming/fueling from player ferried field supplies as available to vehicles. (Providing they can stop close enough to the supplies)
The whole supply thing could be more sophisticated......
Supply types could be
Field (as now)
Material (always available for vehicle repair and general munitions)
Fuel (Available to load if a Fuel store is intact 25% fuel per unit)
Ordinance (Available to load if an Ammo bunker is intact.....Bombs and rockets)
The M3 selects its mix to load much as a tank may choose a mix of HE, AP, Smoke
This could even be developed to enable player supplied landing strips on flat grass tiles away from main metaled fields.
