I wonder if they have to raise their leg knowing there is a ceiling
above. I think their natural attitude during flight involves the
longitudinal axis making an obtuse angle with the ceiling (during slow
speed flights?) , also there is flight attitude which involves all legs
to be yanked up a little .. (reminds me of the skydivers attitude when
they free fall), anyway, they probably dont intend to land there, they
just may stop flying as soon as they touch the ceiling, and their sticky
foot pads do the rest.
