Hi,
In 2.2 trunk - rev 11999 - 2007-09-26 this problem was at least with the new fighter aircraft types I was able to buy. I don't remember names but both new aircraft had this problem when fully equiped.
With 2.2 trunk - rev 12177 - 2007-10-03 I have only tried basic/default interceptor in base and I'm unable to fight UFOs. I did fully equip interceptor at the beginig (shiva gun, two different types of missiles, armor, EMC equipment and targetting computer)
I have not yet tried what happens if I keep default equipment. I will test this later today.
