A en juger par les habits des soldats qui arriment la charge sous le MV-22, le souffle des hélices-pales est très puissant et requiert sans doute une aire d’atterrissage préparée pour éviter un « brownout » (voir https://lf5422.com/2010/08/28/375-helicopteres-americains-perdus-de-2003-a-2009-en-irak-et-en-afghanistan/ )

The MV-22 Osprey is the primary assault support aircraft for the U.S. Marine Corps. It was fielded to replace the CH-46 Sea Knight helicopter and has been deployed to support troops in combat since 2007. The Osprey is unique in that it uses two engines positioned on fixed wing tips housed in nacelles that rotate to allow the MV-22 to land and take off vertically, but achieve much faster flight than a helicopter by tilting the nacelles forward while in flight in a configuration similar to a fixed-wing aircraft.
