Narrative:

I was flying at cruise, 3500 ft from swf to dkk. I had filed a VFR flight plan and activated it in the air. WX at swf was VFR but marginal. WX to the west was reported much better and improving along the route. I started to lose visual contact with the ground. I made a 180 degree turn hoping to return to VFR conditions. 1/2 way through the turn I was in the clouds. I couldn't see anything except white. I had some instrument training and concentrated on holding the airplane level and started to scan the instruments. I told my passenger, also a VFR private pilot, to call ATC, who we had been in contact with, for flight following. He vectored us back to swf. About 5.5 mi from swf we saw the airport and continued visual to land uneventfully. I should have never taken off in marginal conditions. I also should have made a better decision on the direction I made my 180 degree turn perhaps to the right or at a lower altitude would have kept me out of the clouds. I think private pilots should have a little more hood training. If I hadn't worked on my instrument rating I would have been in a worse mess.

Title: SMA TKOF IN MARGINAL VFR CONDITIONS ONLY TO ENCOUNTER FULL IMC. ACFT RETURNS TO LAND AT DEP STATION IN VMC.

Narrative: I WAS FLYING AT CRUISE, 3500 FT FROM SWF TO DKK. I HAD FILED A VFR FLT PLAN AND ACTIVATED IT IN THE AIR. WX AT SWF WAS VFR BUT MARGINAL. WX TO THE W WAS RPTED MUCH BETTER AND IMPROVING ALONG THE RTE. I STARTED TO LOSE VISUAL CONTACT WITH THE GND. I MADE A 180 DEG TURN HOPING TO RETURN TO VFR CONDITIONS. 1/2 WAY THROUGH THE TURN I WAS IN THE CLOUDS. I COULDN'T SEE ANYTHING EXCEPT WHITE. I HAD SOME INST TRAINING AND CONCENTRATED ON HOLDING THE AIRPLANE LEVEL AND STARTED TO SCAN THE INSTS. I TOLD MY PAX, ALSO A VFR PVT PLT, TO CALL ATC, WHO WE HAD BEEN IN CONTACT WITH, FOR FLT FOLLOWING. HE VECTORED US BACK TO SWF. ABOUT 5.5 MI FROM SWF WE SAW THE ARPT AND CONTINUED VISUAL TO LAND UNEVENTFULLY. I SHOULD HAVE NEVER TAKEN OFF IN MARGINAL CONDITIONS. I ALSO SHOULD HAVE MADE A BETTER DECISION ON THE DIRECTION I MADE MY 180 DEG TURN PERHAPS TO THE R OR AT A LOWER ALT WOULD HAVE KEPT ME OUT OF THE CLOUDS. I THINK PVT PLTS SHOULD HAVE A LITTLE MORE HOOD TRAINING. IF I HADN'T WORKED ON MY INST RATING I WOULD HAVE BEEN IN A WORSE MESS.
