Tripods are a bit to big to fit in the Cessna aircraft !  But when I come down to earth I take a tripod for low light planned shots and just recently I had to take pics of small gift sized objects for a web site so the tripod left me hands free to arrange the objects and once i Had the set up ok I had just to repeat the layout.

My monopod is a fairly recent addition and its compact size when folded , quick clip on connector and the fact I can use it for timer activated high shots means its become something worth carrying around.
