MB,
Can you explain how a glider doing 50kt can give a wide berth to a jet airliner doing 250kt+ "?
That's a bit like the papers decribing the collision between a Red Arrow and a yacht off Brighton as "the yacht (doing 5kt?) sailed across the path of the Hawk (>250kt?).
Surely the greater responsiblity in avoiding collisions must go to the faster aircraft.
However, as an ex glider pilot, I do agree with your overall comments.
