Oops. Vaping Pilot Flaps.

[My Batt Hurts]

'Vaping' pilot caused Air China plane to plunge 6,500m (BBC News)

Everyone OK, btw. In case it's blocked, here's the best key bit:

... the co-pilot tried to turn off a fan to stop smoke reaching the passenger cabin without telling the captain, but turned off the air-conditioning unit instead.

(causing oxygen levels to fall).

Apologies if inappropriate or incorrectly placed.

More like incompetence of the co-pilot caused the plane to plunge. If the vapor had caused the AC to shut down blaming the ecig would be more fitting.
