"Tedstriker" wrote A dirigble can produce some lift due to it's size, the air would have so far to travel to get to the top to neutralize the low pressure up there. Incorrect. The reason the dirigble has noticible lift is not how far the air has to travel, but has to do with pure size, (area) and also the Reynolds Number effect. Larger would measure more lift per square foot than the smaller per square foot due to the multiplier of the Reynolds Number in the equation. But on 13" diameter cylinder, any lift produced would be so insignificant, as to be barely measurable. True, it would be barely measurable, but it would be measurable, *if* you wanted to do it. -- Jim in NC
