Narrative:
The airport was having a fly-in. Both aircraft and sailplanes were operating at airport. The aircraft were using runway 18 (a hard surface) and the sailplanes were using runway 9 (a grass strip). The wind was 7 KTS at 150 degrees. I was flying a military aircraft and was asked to do a low approach as I could not land at this airport. I circled the airport at 3000 ft AGL until all traffic was clear. I then entered a long final approach. I announced my position several times. There was also a ford tri motor on approach. We were in contact with each other. I overtook him at approximately a 2.5 mi final. I passed him on his right side with about 750 ft separation. I flew my approach down the right side of the runway (runway 18) so that my wake would not interfere with his course. I was approximately 100 ft west of the runway. There was no other traffic announced on unicom. Half way down the runway, I saw a sailplane at my altitude and flying directly up the runway in the opposite direction. I went underneath him and turned left as he turned to his left. I then called him on unicom and he answered (to my surprise!). He had not heard me nor had he announced his position. He later landed on runway 9 and I left the area.

Title: NMAC BTWN AN OLD MIL ACFT AND A SAILPLANE. NON TWR ARPT SPONSORING A SPECIAL INTEREST ACTIVITY AIR SHOW. SAILPLANE ACTIVITY ACTIVE ON MULTIPLE RWY OPS XING RWYS.
Narrative: THE ARPT WAS HAVING A FLY-IN. BOTH ACFT AND SAILPLANES WERE OPERATING AT ARPT. THE ACFT WERE USING RWY 18 (A HARD SURFACE) AND THE SAILPLANES WERE USING RWY 9 (A GRASS STRIP). THE WIND WAS 7 KTS AT 150 DEGS. I WAS FLYING A MIL ACFT AND WAS ASKED TO DO A LOW APCH AS I COULD NOT LAND AT THIS ARPT. I CIRCLED THE ARPT AT 3000 FT AGL UNTIL ALL TFC WAS CLR. I THEN ENTERED A LONG FINAL APCH. I ANNOUNCED MY POS SEVERAL TIMES. THERE WAS ALSO A FORD TRI MOTOR ON APCH. WE WERE IN CONTACT WITH EACH OTHER. I OVERTOOK HIM AT APPROX A 2.5 MI FINAL. I PASSED HIM ON HIS R SIDE WITH ABOUT 750 FT SEPARATION. I FLEW MY APCH DOWN THE R SIDE OF THE RWY (RWY 18) SO THAT MY WAKE WOULD NOT INTERFERE WITH HIS COURSE. I WAS APPROX 100 FT W OF THE RWY. THERE WAS NO OTHER TFC ANNOUNCED ON UNICOM. HALF WAY DOWN THE RWY, I SAW A SAILPLANE AT MY ALT AND FLYING DIRECTLY UP THE RWY IN THE OPPOSITE DIRECTION. I WENT UNDERNEATH HIM AND TURNED L AS HE TURNED TO HIS L. I THEN CALLED HIM ON UNICOM AND HE ANSWERED (TO MY SURPRISE!). HE HAD NOT HEARD ME NOR HAD HE ANNOUNCED HIS POS. HE LATER LANDED ON RWY 9 AND I LEFT THE AREA.
