Same thing happened to me on my first flight in the first glider I
owned. On pattern entry I went through my pre-landing checklist,
operated the gear handle, opened the spoilers, then heard a load beeping
noise. Closed the spoilers, beeping stopped. It took a fair bit of
contemplation to recognize that the glider might have a gear warning
system. A quick glance at the gear position symbols allowed me to solve
the mystery while still plenty high. I must have forgotten to retract
the gear after release...
