Human Factors
I was the OJTI [On the Job Training Instructor] during this session. Aircraft X was inbound to ILM from the North. Developmental assigned the aircraft a downwind heading for Runway 06 and descended him to 020. Developmental started talking to other aircraft and facilities. I did not notice initially that Aircraft X was descending to 020 instead of 030. I told the Developmental he needed to do something with Aircraft X. Developmental turned and climbed Aircraft X. Aircraft X took the altitude climb but said he did not want to turn due to the antenna and continued on the downwind through the MVA [Minimum Vectoring Altitude].I should have took control of the session more aggressively and not allowed the Developmental to get distracted by other facilities.
CL65 instructor reported not hearing the developmental issue an altitude below the Minimum Vectoring Altitude.
