Feds Want to Equipe Gliders With Transponders and Radios

At any rate, even a high aspect ratio glider with minimal frontal area
presents a rather significant silhouette when wing-up in a bank if it
is seen against contrasting background (unless it is head-on). Perhaps
gliders should be fitted with rotating beacon lights in addition to
transponders. :-)
If seen against a contrasting background, that is key.
