NMAC/Proximity Anecdotes?

For inclusion as examples in various local safety seminars, I've started
collecting credible anecdotal reports of NMACs (loosely defined) between
gliders and other aircraft. I'm particularly interested in incidents or
near-incidents with airliners or other "heavies". I have four such
anecdotes now (including two of my own!) Sample of how used below sigfile .
..

Would appreciate anyone sharing similar information with me . . .any use of
the information would, of course, be stripped of identifying information.

Only interested in CREDIBLE (e.g., first hand, by participant or direct
observer) reports - no "I remember what's- his-name nearly got hit back in
1980" events. As much detail as possible, particularly the best estimate of
proximity and if either aircraft took evasive action. FWIW, I also have the
full report of the only formally documented glider/airliner MAC that I'm
aware of, February 1999 Airbus/G-103 in France.

Thanks in advance . .

Illustrative event report (true):
Summer, 1967, eastern United States. 1-26 and NW Airlines 707, altitude
ca. 4500' MSL, directly over GA airport which, ca. 20 NM away from major
airport. Airliner overtook from behind and passed directly overhead, ca.
100' separation, gear and flaps down. First indication of imminent
collision was dark shadow in cockpit of 1-26. Glider not radio equipped,
both aircraft operating within applicable FARs (at the time!) No evasive
maneuvers by either aircraft.
