Australopithecus: There are airlines and leasing companies that are currently defaulting on new aircraft deliveries from Airbus and Boeing. With aircraft being repossessed the used aircraft market is starting to become awash with cheap aircraft. Values could decline by up to 40% before the world economy is back on track. This presents opportunities for new airlines to start up. A replacement for Virgin Australia will be a good example. They will not have many dollars at risk.
Ps. Boeing has 3 x B717's for sale or lease at present 125Y built 2004.
