I've seen what Halon extinguishers do in a fire, both enclosed and open, as have most of us who've been around long enough. I've also seen what the "next best alternative does" too.
If they ban Halon in aircraft, I might just hang up my wings...I don't EVER want to be in an aircraft aloft without it.
This is a far more serious issue than I've encountered in a long time. Any one have any EU commissioners' phone or Email adresses?
