I won't attempt to count how many of each type each operator has, I know for sure that I would get the numbers wrong.
I have listed the types of aircraft that are actively flying at the moment. Some of the operators own other aircraft that haven't been off the ground in a long time so I have left those off the list.

(I haven't seen their C210 for a while... Abezzi- you've been flying more than I have lately, have you seen/ heard it??)
