Yep, this used to be modelled in AH. I think HTC removed it because if there was a crater on the spawn point you'd blow up immediately on spawn. This caused a lotta people to complain! The above statment is EXACTLY right. As a former AOL Fighter Ops, later, WB Fighter Ops sim player. The trash talk this Spawn point bombing causes is derived from being the recipient of the spawn bomb

Those darn holes lasted 5 min. You couldn't reverse or turn either way you just blew up. Meanwhile the spawn bomber or runway bomber, in the proposed idea, just flies around close collecting kill after kill after kill

The second someone finds out what this crater or craters can do you ain't getting off any forward base. Vulching will take on a new dimension reprisal bombing will escalte and like WB people will log off...
for good . Sure, us regular players had a gentlemans agreement about spawn bombing and wouldn't do it but not everyone's a gentleman. As for the newbies they loved it. " wow I got a 8 kill sortie only needed a 1,000 lb bomb". The newbies wondering why the white text has gone blue.
So, friend who started this thread. I appreciate and understand your concept but beleive me it is way more trouble than HTC would want to afford.
