If I could, Mr. Chairman, I don't know exactly the ages of the Chinook Ds. Dan Ross would know it.
Members will remember that we were advised by the independent panel on the future of the Canadian Forces in Afghanistan, led by John Manley and others, to make sure that we had a heavy-lift capability in theatre if we were going to continue in the mission beyond 2009. That was when we worked out an arrangement with the Americans to buy six existing Chinook Ds for the purpose of the mission. We never intended to bring them back, after the Chinook Fs were envisaged as part of the fleet.
