Narrative:

I was leading a flight of two aircraft on an aerobatic practice mission. We were developing a new maneuver for an air show act in which one airplane rolls around the other airplane. We had been practicing for 30 mins in a designated aerobatic practice area just northwest of turf soaring airport. The start of the maneuver required the #2 ship to begin his pass on my approximately 1000' behind and 500' above me. During the time it took to position the aircraft our heading (approximately 090 degree) took us outside the aerobatic area to the east. Just before the #2 ship started his roll I cleared the area for traffic. When the #2 ship started his roll I watched him through the first 230 degree of his roll before he disappeared under me. Just as he xed the 90 degree point in his roll, I noticed an airline small transport in my 11 O'clock position. I did not call traffic since #2 was clearing the small transport. Closest point between #2 and the small transport was approximately 1400' vertical and 1000' horizontally.

Title: AEROBATIC TEAM HAD CONFLICT WITH SMT SCHEDULED AIR CARRIER SMT ADJACENT TO AEROBATIC PRACTICE AREA.

Narrative: I WAS LEADING A FLT OF TWO ACFT ON AN AEROBATIC PRACTICE MISSION. WE WERE DEVELOPING A NEW MANEUVER FOR AN AIR SHOW ACT IN WHICH ONE AIRPLANE ROLLS AROUND THE OTHER AIRPLANE. WE HAD BEEN PRACTICING FOR 30 MINS IN A DESIGNATED AEROBATIC PRACTICE AREA JUST NW OF TURF SOARING ARPT. THE START OF THE MANEUVER REQUIRED THE #2 SHIP TO BEGIN HIS PASS ON MY APPROX 1000' BEHIND AND 500' ABOVE ME. DURING THE TIME IT TOOK TO POS THE ACFT OUR HDG (APPROX 090 DEG) TOOK US OUTSIDE THE AEROBATIC AREA TO THE EAST. JUST BEFORE THE #2 SHIP STARTED HIS ROLL I CLRED THE AREA FOR TFC. WHEN THE #2 SHIP STARTED HIS ROLL I WATCHED HIM THROUGH THE FIRST 230 DEG OF HIS ROLL BEFORE HE DISAPPEARED UNDER ME. JUST AS HE XED THE 90 DEG POINT IN HIS ROLL, I NOTICED AN AIRLINE SMT IN MY 11 O'CLOCK POS. I DID NOT CALL TFC SINCE #2 WAS CLRING THE SMT. CLOSEST POINT BTWN #2 AND THE SMT WAS APPROX 1400' VERT AND 1000' HORIZLY.
