I trust that gliders always announce take-offs...

More importantly, the ground crew give a good look around the sky before
giving the take up slack signal. The rate of climb is phenomenal - we
don't want to launch if it looks like anyone's about to fly over, it'd
be like the Space Shuttle making a take off call just before blindly
launching into whatever might be overflying the field.

But sometimes mistakes are made, or a plane blends into the sky or... so
really, it's best not to directly overfly the field.
