Skip Pribyl (right), commander of the 493rd Expeditionary Fighter Squadron from Royal Air Force Lakenheath, England, is at Lithuania Air Force Air Base, Lithuania, to accept the "key" to the Baltic air policing mission Sept. 1, 2010, from Lt. Col. Robert Kozak, commander of the departing Polish air force detachment. Passing the key symbolizes the change of command from one unit to the next.
