I think UL here means UltraLight, a minimally regulated, tiny but
MANNED aircraft.

I thought the same, but should like to add that in several countries the
"ultralight" definition allows bigger planes, closer to the newer US
light sport aircraft definition.
Like up here in Canada - 1238 lbs? as long as it stalls under 45 MPH.
It can have a Lycoming IO-235 in it if you want.
