S!
Landing on an enemy field should count as captured!
Landing on your own field, off the runway. The limit for this should be the entire field, that means the entire "sand colored" field just before the grass begins again.
About repairing your plane, you realy think attaching a piece of wing would take 2 minutes?? A more realistic appraoch would be like at least 20 minutes. I will not wait for that, i'll take myself a new bird.
What i would like to see is that whenever i get a kill, i get my kill marked on my fuselage!

Five kills in a row, means five of those american stars on my 109! Yeah!
Thanks,
