I think the last major instance of passengers being saved by life jackets was ALM 980 in 1970 which was a DC-9 that ditched after running out of fuel.

Originally posted by QuenchThat was the one I had in mind. I did not realise that everyone that exited the aircraft survived lifejacket or no.
IIRC a number of passengers drowned because they inflated their lifejackets inside the aircraft and then could not swim down and out
hmmm
By this logic, perhaps removing life jackets will save more lives! hmmm

The chances of ever needing a life-vest is very slim. With all those ETOPS aircraft around, it is amazing that you hardly ever hear of even a divert. For life-vests to be of any use, it needs to be a nice controlled landing on water (very tricky with engines under the wing), with the ability to get out and use them. Even then in cold water and far from rescue, the only thing a life-vest will do is to make it easier for the SAR team to collect the bodies... And those ditchings, where the plane nicely skips on the water, then settles and everyone gets out into the slides coupling as rafts happen only in Hollywood. Look at the last two - both resulted in the partial disintegration of the aircraft.
It is just one of those holy cows no regulator would be willing to touch - just look at the amazing response to a perfectly rational (and legal) decision by JAZZ.another ADC refugee

Just an afterthought to the cost savings aspect:
From our own experience and anecdotal info from other carriers, in a year about 10-20% of the total onboard life-vest stock get "taken as souvenirs" by passengers. Seat cushions are perhaps less attractive.another ADC refugee

Form 33000ft that's 99 NM, or 183km, or 114 statue miles.

This is a RED HERRING, we all fly aircraft that are not equipped with vests.
I don't know of any US operator flying domestically that have life vests on their aircraft. Aircraft flying over water are another issue. At one time Alaska considered removing the vests from all their aircraft because even though they were over water between SEA and ANC because they were close enough to the coast to meet the requirement.
I don't know if they did or not.Last edited by Dmmoore; 2008-08-26, 22:54.Don

Huh. No domestic flights have vests?
I disagree as I think I've seen several vest demonstrations in recent years for strictly over-land flights and was wondering why they even ranked a briefing?
One thing not emphasized (maybe one person mentioned it) here is "in an emergency, your seat cushion can be used as a flotation device".
I don't know if that applies to all aircraft, but it by some miracle I survive a ditching, I am perfecly happy to use my seat cushion as opposed to donning the floatie vest with the duck head (some sarcasm at the very end).
So save the expense of buying them, the expense of keeping them certified, and the expense of hauling them, as implied above, the number of saves versus the number of drownings makes them super incredibly unlikely to save the day.Les règles de l'aviation de base découragent de longues périodes de dur tirer vers le haut.

For aircraft with engines below the fuselage, such as the Boeing and Airbus medium and long haul aircraft, could the solution be a way of having the engines detach upon impact or before impact so that the aircraft would not be torn apart by the forces? Part of why ET 961 was destroyed is because the engines dragged in the water.

I wouldn't feel safe on any aircraft that had a system to detach the engines. I know that some aircraft are designed that engines will detach in extreme vibrition that could endager the a/c but I'm a firm believer that the engines should remain firmly attached
I also think that life jackets on these kinds of flights are a waste of time. The light and whistle might be still a nice thing to keep though

Speaking of which, many drowned because they inflated their vest prior to the ditch. How do you get out of such asituation with a seat cushion under your arm? Okay, your head won't be stuck to the ceiling* but I'm not sure at all you'll get out through whatever opening you find if you carry a seat cushion.
