There is still a fairly large RCS, even on a glass bird -- engine,
pilot, electronics, wiring, antennae, landing gear, etc.
Not on ATC radar there ain't.
Funny.. local ATC calls glider traffic to the inbound airliners.. we (the
gliders) are not talking to ATC.. but they can see our glass (and metal)
birds just fine.. they just don't know our altitude.. LAS TRACON
