Here is my best idea,
You can post your question directly to Bruce Drum (Mr. Miami), Bruce retired in 2007 with the title; Deputy Director of Operations (Retired) - for Miami Intl. Airport.
At the end Bruce was responsible for the operations, security and maintenance of Miami International Airport and the five general aviation airports. After a career of 30 years 7 months!
He has been taking photographs of all the airliners the entire 30 years!!!
Anyway, you can post a question to him and I'm sure he give you some personal insight, I might add, any security/airport people you may run into, Bruce Drum is a good name to know!!!
I'm sure he'll be aware of every BBJ based in the area.
