unceremoniousというのは「ぶしつけな、無遠慮な」という意味でしょうか。再び不時着事故を起こしたこの機種にはふさわしいとも思えますが...（Nat）
Osprey aircraft deployed for first time in support of Marine One
(CNN) – Marine Corps MV-22 Ospreys, aircraft that take off vertically, provided a dramatic new look for President Barack Obama’s travel detail as he and the first lady began a Martha’s Vineyard vacation on Saturday.
The Ospreys – making their presidential debut - shuttled White House staff, media and Secret Service members from Coast Guard Air Station Cape Cod.
The sleek tilt-rotor aircraft can take off like a helicopter but fly like an airplane.
The Marines say the Ospreys are twice as fast, can travel six times farther and are capable of carrying three times the weight of the Vietnam-era CH-46E helicopters which have supported missions involving the president.
There are no plans yet to have the president fly in the MV-22s.
The Osprey has raised some safety concerns over the years. It earned the unceremonious nickname “the Widowmaker” after crashes during initial development and testing.
