I couldn't say for sure without seeing it first-hand, but you also have to realize how much smoke is generated by an airplane. For example, if you turned on a good smoke system in an average living room for only 3-4 seconds (Don't try this at home kids... We're professionals), You wouldn't be able to see your hand in front of your face. (No, I didn't do this in my living room, but you should have seen the look on all of the neighbors faces when I opened the garage door! )
