As a former USAF FF, we always wore the full hood on the crash side. I've noticed though that at least at my former base, they are no longer being used. I've heard that is because it was very difficult to wear a BA with the hood.(It was) Yesterday though I saw video of the emergency landing at LAX and there were the hoods and no BAs. Curious me. What's the preference now. Was it just those wacky LA guys
