AIRCRAFT | A320 Oxygen Mask Operating Procedure 

Personally, I don’t squeeze the tabs when removing the mask, because squeezing the tabs inflates the straps whilst still in the box. Just makes it more likely to catch on something on the way out. Pull out, then squeeze.

@Mr3wheeledbike Yep

is this air plane stuff?

Would it work for thé coronavirus?

Lol, I've watched 3 different videos and they all do it differently.

Won't pure oxygen kill you?

737 masks look much safer
