From a very reliable source who meet with one ACE's founders (Mckenzie). All crew are still on the 10 course, Gemini will be doing the contract until ACE has it'a aircraft on line. They have even been to the GTAA's hangar in YYZ to inquire about renting the bay next to Westjet's for the 10's maintenance.
Why ACE chose the DC-10 still boggles my mind, it is the most labour intensive aircraft I know. I think the money they saved on leasing is going to cost them in delays and maintenance. I know guys who say that the #2 eng on the 10 paid their mortage off 10 years early. Either way good luck to ACE, at least the contracts staying Canada.
