Narrative:

En route to pvd airport, receiving advisories from ocean approach. Small transport passed above us, climbing nwbnd, missing us by approximately 100'. We queried the controller, who merely sought to cover his error on the tape, by saying that he had called traffic twice and we had not answered. This was an outright lie as both myself and my first officer had been maintaining a continuous outside scan and listening watch on 127.9 MHZ. I identified the traffic as an small transport, a call to groton tower confirmed a recent VFR small transport departure. Despite our vigilant watch for traffic, the aircraft was able to approach undetected from our 1:30 position, partly because of the poor cockpit window design which tends to obscure viewing in the 10-11 O'clock 1-2 O'clock position. A call to ocean approach on the ground (telephone) provided a new answer. Ocean claimed traffic was nontransponder equipped and a primary target only so they did not call the traffic. Despite our vigilant outside scan and radar monitoring we were still nearly killed in a near midair collision. I do not have any suggestions as to how to avoid this type incident.

Title: TRAFFIC ADVISORIES BUT HAS NMAC WITH SMT CLIMBING.

Narrative: ENRTE TO PVD ARPT, RECEIVING ADVISORIES FROM OCEAN APCH. SMT PASSED ABOVE US, CLIMBING NWBND, MISSING US BY APPROX 100'. WE QUERIED THE CTLR, WHO MERELY SOUGHT TO COVER HIS ERROR ON THE TAPE, BY SAYING THAT HE HAD CALLED TFC TWICE AND WE HAD NOT ANSWERED. THIS WAS AN OUTRIGHT LIE AS BOTH MYSELF AND MY F/O HAD BEEN MAINTAINING A CONTINUOUS OUTSIDE SCAN AND LISTENING WATCH ON 127.9 MHZ. I IDENTIFIED THE TFC AS AN SMT, A CALL TO GROTON TWR CONFIRMED A RECENT VFR SMT DEP. DESPITE OUR VIGILANT WATCH FOR TFC, THE ACFT WAS ABLE TO APCH UNDETECTED FROM OUR 1:30 POSITION, PARTLY BECAUSE OF THE POOR COCKPIT WINDOW DESIGN WHICH TENDS TO OBSCURE VIEWING IN THE 10-11 O'CLOCK 1-2 O'CLOCK POSITION. A CALL TO OCEAN APCH ON THE GND (TELEPHONE) PROVIDED A NEW ANSWER. OCEAN CLAIMED TFC WAS NONTRANSPONDER EQUIPPED AND A PRIMARY TARGET ONLY SO THEY DID NOT CALL THE TFC. DESPITE OUR VIGILANT OUTSIDE SCAN AND RADAR MONITORING WE WERE STILL NEARLY KILLED IN A NEAR MIDAIR COLLISION. I DO NOT HAVE ANY SUGGESTIONS AS TO HOW TO AVOID THIS TYPE INCIDENT.
