How did you do that?
Whenever I am shot down, I ride the chute all the way to the ground.
If I am near an enemy or friendly field and there is action there, I sneak up approaching from the proper radial and use buildings and trees to cover from the auto ack.
If done right, you can get near where the planes spawn and simply put rounds into planes that spawn near you.
A Vguys mission spawned right in front of me so I put a single round into the cockpit of 16 different planes.
5 minutes later, I was rewarded with a whole buffer worth of kills when they all bailed together because they had been discovered.
Whenever I shoot someone down and see him riding his chute all the way, I bail nearby in the hopes of a foot chase shootout.
