Narrative:

Aircraft #2 departing from 4g3, VFR advisories to let parachute jumpers out at 12500 ft. ZOB denied services due to traffic. 12500 ft is above my altitudes. I terminated radar service. Jump is in class east airspace -- no authority/authorized needed for jump. Aircraft #1 departing 4g3 (same parachute school as I understand it) to let jumpers out at 4500 ft (X3). I gave radar service and advised of company jump aircraft above him and asked if he had communication with that aircraft -- he said no. #1 advised 1 min before jump. I had no traffic below him. I advised him I no longer knew position of #2, but I thought he appeared to be 'setting-up' to jump also. #1 acknowledged and continued with his jump. Perhaps seconds before #1 jumped I advised him what I thought was #2 was descending. He immediately turned 90 degrees and left the jump area. I believe it is extremely unsafe for multiple aircraft to be using the same 'drop zone' for parachute jumpers, at the same time without having radio communication to coordinate their jumping sequence independently of ATC. The perception that ATC will coordinate their jump sequence is erroneous and could lead to fatalities.

Title: TRACON CTLR EXTENDS HIMSELF TO RESOLVE DUAL PARADROP ACTIVITY WHEN NONE IS REQUIRED. CTLR SITES TWO INSTANCES DURING AN OP SHIFT WHEN HE PERCEIVED HE NEEDED TO INTERVENE TO RESOLVE SITS.

Narrative: ACFT #2 DEPARTING FROM 4G3, VFR ADVISORIES TO LET PARACHUTE JUMPERS OUT AT 12500 FT. ZOB DENIED SVCS DUE TO TFC. 12500 FT IS ABOVE MY ALTS. I TERMINATED RADAR SVC. JUMP IS IN CLASS E AIRSPACE -- NO AUTH NEEDED FOR JUMP. ACFT #1 DEPARTING 4G3 (SAME PARACHUTE SCHOOL AS I UNDERSTAND IT) TO LET JUMPERS OUT AT 4500 FT (X3). I GAVE RADAR SVC AND ADVISED OF COMPANY JUMP ACFT ABOVE HIM AND ASKED IF HE HAD COM WITH THAT ACFT -- HE SAID NO. #1 ADVISED 1 MIN BEFORE JUMP. I HAD NO TFC BELOW HIM. I ADVISED HIM I NO LONGER KNEW POS OF #2, BUT I THOUGHT HE APPEARED TO BE 'SETTING-UP' TO JUMP ALSO. #1 ACKNOWLEDGED AND CONTINUED WITH HIS JUMP. PERHAPS SECONDS BEFORE #1 JUMPED I ADVISED HIM WHAT I THOUGHT WAS #2 WAS DSNDING. HE IMMEDIATELY TURNED 90 DEGS AND LEFT THE JUMP AREA. I BELIEVE IT IS EXTREMELY UNSAFE FOR MULTIPLE ACFT TO BE USING THE SAME 'DROP ZONE' FOR PARACHUTE JUMPERS, AT THE SAME TIME WITHOUT HAVING RADIO COM TO COORDINATE THEIR JUMPING SEQUENCE INDEPENDENTLY OF ATC. THE PERCEPTION THAT ATC WILL COORDINATE THEIR JUMP SEQUENCE IS ERRONEOUS AND COULD LEAD TO FATALITIES.
