At FL350, if the decompression was rapid the time of useful consciousness (TUC) is 'round 30-60 seconds, dependin' on various factors.
A slower rate would have provided more time fer the crew, provided tha cabin altitude didn't get too high too quickly an' they got their masks on.
Interestin' to note the AF talkin' heads are spinnin' a lightning strike; weather related cause this early in the game...
