Narrative:

While working departure for navy pensacola, I received a pointout on an E120 (air carrier a) that was deviating around a thunderstorm. I was told the aircraft would make a wide right downwind to avoid WX which would cross my departure path. A flight of 2 T-2's departed navy pensacola on a SID, I observed the E120's altitude and determined no action would be necessary. After taking care of other duties, I reevaluated the situation and observed that air carrier a had not continued directly to the downwind, but had made more maneuvers to avoid the WX, which placed him in a conflicting situation with MTR B. At this time the aircraft were one atop of the other, air carrier a's altitude 7300 ft descending. MTR B 5700 ft climbing. I stopped MTR B at 6000 ft. At the same time, the flight paths crossed in an opposite direction manner. MTR B reported he almost had a mid air with a commuter. I advised MTR B that the commuter was 1000 ft above him, which he was, until the flight paths crossed, at which time the commuter descended rapidly. MTR B's response was that it didn't look like 1000 ft. Possibly, his visual perspective was illusive, due to the climb and descent attitude of each aircraft. I never observed less than 1000 ft until the aircraft had passed.

Title: FLC OF MIL B RPTS NMAC WITH ACR A.

Narrative: WHILE WORKING DEP FOR NAVY PENSACOLA, I RECEIVED A POINTOUT ON AN E120 (ACR A) THAT WAS DEVIATING AROUND A TSTM. I WAS TOLD THE ACFT WOULD MAKE A WIDE R DOWNWIND TO AVOID WX WHICH WOULD CROSS MY DEP PATH. A FLT OF 2 T-2'S DEPARTED NAVY PENSACOLA ON A SID, I OBSERVED THE E120'S ALT AND DETERMINED NO ACTION WOULD BE NECESSARY. AFTER TAKING CARE OF OTHER DUTIES, I REEVALUATED THE SIT AND OBSERVED THAT ACR A HAD NOT CONTINUED DIRECTLY TO THE DOWNWIND, BUT HAD MADE MORE MANEUVERS TO AVOID THE WX, WHICH PLACED HIM IN A CONFLICTING SIT WITH MTR B. AT THIS TIME THE ACFT WERE ONE ATOP OF THE OTHER, ACR A'S ALT 7300 FT DSNDING. MTR B 5700 FT CLBING. I STOPPED MTR B AT 6000 FT. AT THE SAME TIME, THE FLT PATHS CROSSED IN AN OPPOSITE DIRECTION MANNER. MTR B RPTED HE ALMOST HAD A MID AIR WITH A COMMUTER. I ADVISED MTR B THAT THE COMMUTER WAS 1000 FT ABOVE HIM, WHICH HE WAS, UNTIL THE FLT PATHS CROSSED, AT WHICH TIME THE COMMUTER DSNDED RAPIDLY. MTR B'S RESPONSE WAS THAT IT DIDN'T LOOK LIKE 1000 FT. POSSIBLY, HIS VISUAL PERSPECTIVE WAS ILLUSIVE, DUE TO THE CLB AND DSCNT ATTITUDE OF EACH ACFT. I NEVER OBSERVED LESS THAN 1000 FT UNTIL THE ACFT HAD PASSED.
