Narrative:

Took off from 5v4 for jump sortie with 5 jumpers and 1 non jumping observer. Dropped jumpers at 17500 ft MSL, just northwest of 5v4. Flew 1 mi northeast of 5v4 for descent. 45 degree left bank and 120 mph used for descent. At approximately 12500 ft MSL colorado springs approach control released me from radar control. As I descended through 10000 ft MSL a military T-3 appeared in my windshield. I had to increase left bank to 90 degrees to avoid a mid air collision. I had made a radio call to eagle controller on 123.5 on climb out, 1 min before jumpers away, and after jumpers away. The T-3 appeared to be heading across the middle of the traffic pattern of 5v4. After the close call, I advised eagle controller on 123.5 that one of their aircraft was too close to 5v4 for safety. The military has shown no interest in routing these trainers a safe distance and route away from 5v4 which has been an established drop zone for many yrs.
