An MSNBC newscast just postulated the theory that ex-OSS spy Julia Child was reactivated into service after her staged and fictitious death. Both she and ex-CIA covert operative Valerie Plame, who was also reinstated per executive order, were sent on a secret mission to neutralize the pilots while posing as Australian party girls, or maybe not, knock them out with Halston perfume, and fly the route Bing Crosby and Bob Hope did on the Road to Zanzibar. The news service is still developing a working motive for the action, possibly that the plane may be in Pakistan, as Rupert Murdoch posited, where bin Laden was. The president could repeat his feat of getting Mr bin Laden again to boost his mid 30s approval rating.
You forgot the part where Bing Crosby was involved in making a porno film to help the CIA to overthrow a dictator (yes it really did happen)
