mmmmh seems you dont have much experience in the business.
The DC 10 is owned an operated by own crews, the 742 and the MD11 are in Wet Lease, its not like they operate a fleet of different a/c, its just until they find other a/c on the market, which is not easy at the moment.
You can operate 10 diff a/c types on a wet lease, all ops is done by the wet lease company, so no big deal.
New a/c shoud come in 2008.
BTW the company is called Trade Winds Cargo.
