affixed to the inflatable slides which double for rafts in the case of an on water landing.
Heli-phile, again that does not make sense to me because it would not be 'logical' in the minds of the beancounters... it also assumes that particular slide/raft makes it off the airframe.
Are they any actual, documented airlines who have this setup? I'm just really curious now... as I said I have flown on more than 10 aircraft types and have never seen/heard of this setup...
