I see your point. Thanks. ...was mixing bouancy with floating.
(i.e. that an object in a more dense medium still "feels lighter" even if fully immersed. Doh! e.g. Water tanks used to train crews for space-walks!)
I guess I need to try to calculate the density of a Dragonfly, compare to the density of air; and then with the density of air at higher pressures... that would provide a % improvement in natural bouancy. A lunch-time "project".
{But would the more-dense air create more drag and thus make it harder to move?}

What I was thinking about, was arguements about whether a sinking ship would ever go down far enough that it hit water at such a high pressure that it stops sinking. Turns out "no". As long as the ship is denser than the water, it will keep sinking, and it always is. (The twist was apparently that at high enough pressure the water would turn into ice - and
that would stop the ship sinking... but it wouldn't occur on Earth.).

Apology to Toothdust.
