Actually the rules were modified:
Hangers take 1.5X normal to destroy. So it "Should" be about 4.5K lbs. This seems to vary depending on how direct the hit is, so perhaps 3X500kg's will do it.
CV's are set to 2.5X normal to destroy, so it takes ~20K lbs of bombs to take out.
Captures now take 20 troops
Fields for new aircraft vary per side, and CO's of the respective sides can aquaint you with where they'll be.
Pilots are encouraged to sign up and fly for one side, gaining access to forums by PM'ing the CO for which ever side they sign up for.
From what I understand, downtimes are set to 60 mins.
