Narrative:

On 4/sun/89, while flying at 8500' over the bos TCA on a VFR flight from hyannis, ma, to moultonboro, nh, under radar control, I experienced a near miss with a commercial jet liner. The WX very clear. I was about 5 mi south of the bos VOR on a heading of approximately 340 degree. My wife and I observed a target at about 1 O'clock, several thousand ft below us. It appeared to have its landing lights on--it appeared very small because we were looking at it head on. I saw smoke trailing it, so concluded it was a jet. We watched it for sometime. It appeared headed directly at us. At the last minute, when we were convinced we were going to hit, I turned my aircraft to my left (away from the approaching aircraft) and descended rapidly at reduced power. I saw the jet liner go over us and I believe a bit behind us. To this point we had had no communications whatsoever from the controller about this target, nor had we heard the controller talk to the target about us. I stabilized our aircraft and turned our aircraft back toward 340 degrees. The controller did communicate then and was upset because she said I was controled at 8500' and the jet liner was controled at 8000'. I told her that I didn't know that (nobody had told us that) and it was very apparent to us that we were going to be hit. We clearly could not out climb or outrun the jet--our only realistic option was to dive away from the target.

Title: CLOSE PROX GA-SMA FLYING VFR OVER THE BOS TCA AND ACR CLIMBING OUT.

Narrative: ON 4/SUN/89, WHILE FLYING AT 8500' OVER THE BOS TCA ON A VFR FLT FROM HYANNIS, MA, TO MOULTONBORO, NH, UNDER RADAR CTL, I EXPERIENCED A NEAR MISS WITH A COMMERCIAL JET LINER. THE WX VERY CLEAR. I WAS ABOUT 5 MI S OF THE BOS VOR ON A HDG OF APPROX 340 DEG. MY WIFE AND I OBSERVED A TARGET AT ABOUT 1 O'CLOCK, SEVERAL THOUSAND FT BELOW US. IT APPEARED TO HAVE ITS LNDG LIGHTS ON--IT APPEARED VERY SMALL BECAUSE WE WERE LOOKING AT IT HEAD ON. I SAW SMOKE TRAILING IT, SO CONCLUDED IT WAS A JET. WE WATCHED IT FOR SOMETIME. IT APPEARED HEADED DIRECTLY AT US. AT THE LAST MINUTE, WHEN WE WERE CONVINCED WE WERE GOING TO HIT, I TURNED MY ACFT TO MY LEFT (AWAY FROM THE APCHING ACFT) AND DSNDED RAPIDLY AT REDUCED PWR. I SAW THE JET LINER GO OVER US AND I BELIEVE A BIT BEHIND US. TO THIS POINT WE HAD HAD NO COMS WHATSOEVER FROM THE CTLR ABOUT THIS TARGET, NOR HAD WE HEARD THE CTLR TALK TO THE TARGET ABOUT US. I STABILIZED OUR ACFT AND TURNED OUR ACFT BACK TOWARD 340 DEGS. THE CTLR DID COMMUNICATE THEN AND WAS UPSET BECAUSE SHE SAID I WAS CTLED AT 8500' AND THE JET LINER WAS CTLED AT 8000'. I TOLD HER THAT I DIDN'T KNOW THAT (NOBODY HAD TOLD US THAT) AND IT WAS VERY APPARENT TO US THAT WE WERE GOING TO BE HIT. WE CLEARLY COULD NOT OUT CLB OR OUTRUN THE JET--OUR ONLY REALISTIC OPTION WAS TO DIVE AWAY FROM THE TARGET.
