Well… if smoking wasn’t prohibited the root cause was the leaky oxygen mask…
> Incredibly, at the time of the incident, EgyptAir pilots were allowed to smoke in the cockpit – a rule that has since changed.
From the article. The valve was set to the wrong position. Headline is bad.
something being prohibited or not doesn't really change the root cause :P. just click bait i guess. lots of things can cause sparks.
Name five that are permitted in a cockpit?
static electricity, switches, carbon brushes in ventilation fan motors
That's the airplane itself, ie. you're suggesting that the airplane itself is so dangerous that other risks don't add significantly to the total danger.
