Big, fat thanks @ you, knuckles, for providing "external view" to double check on my issue!

It seems my bombs did actually work from the start, but I went from wrong assumptions, which, on full-real servers, obviously DO sometimes happen (see other threads about the matter)

.
S!
Edit:
Oh, while I just remember it: A follow-up on "bombing on plain countryside" would be: What about bombing airfield runways? Are the craters which you blow into mostly "plain soil" (i.e. on the enemy's runway) sufficient to take that runway out for some period of time? Or is it pointless?
Maybe this should be tested as well
