NMAC BETWEEN ACR MLG AND GLIDER.

Narrative

ENRTE BOS DIRECT MHT; RADAR VECTORS TO VISUAL APCH TO RWY 35 MHT; NORMAL FLT AND LNDG. ENRTE TO MCO WE RECEIVED AN ACARS MESSAGE FROM OUR OPS TO CALL MHT TWR UPON ARR IN MCO. THE CAPT DID SO AND WAS TOLD THAT A SAILPLANE IN TOW RPTED A NEAR MISS WITH US APPROX 8 MI SE OF MHT. HE WAS ALSO TOLD THAT THE TOW PLANE SAW AND RPTED NOTHING. FROM HIS (THE SAILPLANE PLT) RPT; WE ESTIMATE BEING 4000'. OUR FINAL CRUISE ALT FROM BOS WAS 7000' MSL. WE SAW NOTHING AND TOOK NO EVASIVE ACTION. I WOULD LIKE TO MENTION THAT THE CAPT DID RPT A SAILPLANE THAT HE SPOTTED WELL BELOW US--IN FACT; BELOW THE 3800' BROKEN LAYER WE WERE ABOVE AT A POINT INSIDE THE MHT CTL ZONE WHILE WE WERE ON A VECTOR FOR THE VISUAL APCH TO RWY 35 MHT. HE DID NOT SEE A TOWPLANE THOUGH; ONLY THE SAILPLANE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: FLT CREW HAS HEARD NOTHING FURTHER FROM THE INCIDENT. THE GLIDER PLT THAT FILED RPT SAID HE FELT THE JET WASH SO THAT COULD HAVE BEEN SOME DISTANCE AFTER JET PASSED. RPTR SAID GLIDER PLT MAY HAVE RECONSIDERED FILING NMAC AS WAS IN AREA WHERE DID NOT BELONG. THIS RPT WAS FILED IN CASE WE GET MORE FROM SAME AREA.
