The SAMs and escort fighters around Stonehenge, plus Stonehenge itself, on Ace. 'nuff said.

Both Stonehenge and Chandelier had AA defenses, in the forms of AA guns, SAMs, and escort fighters (Yellow Squadron or Strigon Team). Chandelier did have more AA, from the ships, but there weren't that many. However, Burner is absolutely correct. You can get shot down from Stonehenge even from the first minute of the mission. Chandelier will never shoot you down, never, until you're flying into the barrel at the end, which is extremely easy to overcome as long as you've got the timing right. Stonehenge? I was having problems just avoiding the turret fire while I aimed for the turrets themselves! And Yellow Squadron had me flying in circles for five minutes straight, at least.
