Spooks and the Man Kicked Off Plane For Not Wearing Mask In Between Bites Of Food

[727Sky]

Depending on the make an the model of airplane once airborne the cabin air is new air every 4 to six minutes. A 737 if I remember correctly is ever 4 minutes. This is done with the air cycle machines (2 on a 2 engine jet) and the pressurization of the cabin. There are outflow valves where all the used air is vented overboard. IMO you are more likely to get a bug by touching something infected and then your mouth or eyes...
