inside the cabin as compared to the outside air". I was thinking that the faster air
outside should be a lower pressure than inside the cabin, but I stand (sit) corrected....the air rushing outside the cabin "pulls" the air from the cabin, causing a lower density/pressure relatively.
btw...I don't mean to sound arrogant, I'm just a stickler for spelling (not typosesses)....it's Bernoulli
