Narrative:
After dropping skydivers, I called ZAB in the descent and he reported traffic 1/4 mi east of the airport eastbound. A discussion followed after the pilot of the eastbound bonanza reported skydivers above his altitude, 1/4 mi at his 12 O'clock position. ZAB questioned whether I had heard his traffic reports. I replied I had overheard him working traffic with another jump aircraft. ZAB stated that he called both jump aircraft. I never replied to any traffic report and only overheard conversation that I believed specific to the other jump aircraft's position. ZAB did not report any specific traffic to me when I made my 2 min call. Remedy: restrict airspace around intense activity drop zones in the interest of public safety. Require readback to verify who is actually participating in your conversation. I believe this is already in place. I'm not trying to point a finger at a controller or another pilot here. I believe all parties involved share some percentage of responsibility. The point is: pilots and controllers are people who deal with variable workloads. High workload and division of attention should not subject life and property to risk.

Title: PREMATURE RELEASE OF SKYDIVERS FROM A SHORTS SC7 WHOSE 'LOAD' FALLS ONE QUARTER MI IN FRONT AND ABOVE A BONANZA TRANSITING THE CLASS E AIRSPACE NEAR E60, AZ.
Narrative: AFTER DROPPING SKYDIVERS, I CALLED ZAB IN THE DSCNT AND HE RPTED TFC 1/4 MI E OF THE ARPT EBOUND. A DISCUSSION FOLLOWED AFTER THE PLT OF THE EBOUND BONANZA RPTED SKYDIVERS ABOVE HIS ALT, 1/4 MI AT HIS 12 O'CLOCK POS. ZAB QUESTIONED WHETHER I HAD HEARD HIS TFC RPTS. I REPLIED I HAD OVERHEARD HIM WORKING TFC WITH ANOTHER JUMP ACFT. ZAB STATED THAT HE CALLED BOTH JUMP ACFT. I NEVER REPLIED TO ANY TFC RPT AND ONLY OVERHEARD CONVERSATION THAT I BELIEVED SPECIFIC TO THE OTHER JUMP ACFT'S POS. ZAB DID NOT RPT ANY SPECIFIC TFC TO ME WHEN I MADE MY 2 MIN CALL. REMEDY: RESTRICT AIRSPACE AROUND INTENSE ACTIVITY DROP ZONES IN THE INTEREST OF PUBLIC SAFETY. REQUIRE READBACK TO VERIFY WHO IS ACTUALLY PARTICIPATING IN YOUR CONVERSATION. I BELIEVE THIS IS ALREADY IN PLACE. I'M NOT TRYING TO POINT A FINGER AT A CTLR OR ANOTHER PLT HERE. I BELIEVE ALL PARTIES INVOLVED SHARE SOME PERCENTAGE OF RESPONSIBILITY. THE POINT IS: PLTS AND CTLRS ARE PEOPLE WHO DEAL WITH VARIABLE WORKLOADS. HIGH WORKLOAD AND DIVISION OF ATTN SHOULD NOT SUBJECT LIFE AND PROPERTY TO RISK.
