I find it hard to believe that any company (even Arrow in Miami) would be able to allow crewmembers to be current and qualified on 4 different types. Perhaps they went to the sim, but if they flew 4 different types on a regular basis, I can't imagine that being in the ops manual as being legal. 2 different types; yes, 4 different types; jail time (even in MIA in the 80's).
