Narrative:

While departing the ft myers airport (rsw) we were on a vector heading 360 degree climbing through approximately 9700 ft for 10000 ft assigned when the captain yelled 'traffic.' I was flying and had been looking straight ahead. Skies were mostly clear with a few scattered cumulus clouds. I looked left and saw a blue and white small aircraft pass over the top of the cockpit at 50-100 ft. My first thought was that he would hit our tail. He was wbound and did not appear to have seen us. Our TCASII was on and gave no indication of traffic. Departure control said they saw no traffic in our vicinity. Apparently our traffic was at 10000, VFR without a transponder. I was thinking about light aircraft traffic, since we were being held down low for a considerable time. My attention was divided between TCASII, looking outside and monitoring the level off. I don't know why we didn't see the traffic. Possibly his position was high enough to be blocked by the wind screen. He probably did not see us due to his low wing confign. This could just as easily have been a hit as a miss. We were just lucky. There is no excuse for this. All airplanes need to have and use transponders!

Title: CLOSE PROX ACR-MLG GA-SMA N OF RSW.

Narrative: WHILE DEPARTING THE FT MYERS ARPT (RSW) WE WERE ON A VECTOR HDG 360 DEG CLBING THROUGH APPROX 9700 FT FOR 10000 FT ASSIGNED WHEN THE CAPT YELLED 'TFC.' I WAS FLYING AND HAD BEEN LOOKING STRAIGHT AHEAD. SKIES WERE MOSTLY CLR WITH A FEW SCATTERED CUMULUS CLOUDS. I LOOKED L AND SAW A BLUE AND WHITE SMA PASS OVER THE TOP OF THE COCKPIT AT 50-100 FT. MY FIRST THOUGHT WAS THAT HE WOULD HIT OUR TAIL. HE WAS WBOUND AND DID NOT APPEAR TO HAVE SEEN US. OUR TCASII WAS ON AND GAVE NO INDICATION OF TFC. DEP CTL SAID THEY SAW NO TFC IN OUR VICINITY. APPARENTLY OUR TFC WAS AT 10000, VFR WITHOUT A TRANSPONDER. I WAS THINKING ABOUT LIGHT ACFT TFC, SINCE WE WERE BEING HELD DOWN LOW FOR A CONSIDERABLE TIME. MY ATTN WAS DIVIDED BTWN TCASII, LOOKING OUTSIDE AND MONITORING THE LEVEL OFF. I DON'T KNOW WHY WE DIDN'T SEE THE TFC. POSSIBLY HIS POS WAS HIGH ENOUGH TO BE BLOCKED BY THE WIND SCREEN. HE PROBABLY DID NOT SEE US DUE TO HIS LOW WING CONFIGN. THIS COULD JUST AS EASILY HAVE BEEN A HIT AS A MISS. WE WERE JUST LUCKY. THERE IS NO EXCUSE FOR THIS. ALL AIRPLANES NEED TO HAVE AND USE TRANSPONDERS!
