Someone asked whether there was any accident where ogygen
generators/supply would have save lives.

In the summer of 1999,  that small plane with the famous golfer is
perhaps an example.  While the true cause may never be known, assuming
proper behaviour by pilots, they were not able to don the oxygen masks
in time.

But such incidents are rare, aren't they ?

Have they ever considered changing the whole "oxygen" thing with just
ample supply of clean air ? Should there be a fire/smoke in the cabin,
by stopping the cabin ventilation system and just feeding air through
such masks, would this not provide the passengers with breathable air
and would this not leave the fire with less oxygen to burn/survive  ?
(or at least slow it down).

In other words, don't recycle any cabin air, and feed passengers only
fresh air from outside through a mask, at a pressure similar to what the
individual air vents would supply.

Since it was shown that in most accidents, passengers die from smoke
inhalation, shouldn't that be more of a priority than to provide a few
minutes' worth of oxygen during a descent ?
