pop the chute at a low altitude, then they can't get you! then you can run around and create hate and discontent with impunity!
Otherwise as Daddog and others have said when your feet touch the ground you should exit.
For this one instance, it wasn't necessary, we got jumped right after our flight group spotted the ships under our position...Saltee was out of ack range from the ships and us fighters were trying to protect the bombers as they made their run. I can see the argument if we were at low enough alt to make a difference but that wasn't the case here.
In here, vox is always available. Running your gob on TS, while floating in AH, is the equivalent of using a PRC-90 during WWII...it just didn't happen. I grok.
