A Navy F-18 Hornet escorts the new Navy variant of the F-35 Lightning II as they fly over the crowd during the 2011 Joint Service Open House at Joint Base Andrews, Md., May 21. This is the first time this aircraft has performed at a public event of this nature. The JSOH affords the public an opportunity to meet the men and women of the Armed Forces and to see military equipment through the efforts of active duty, guard and reserve servicemembers, as well as civilians employees, retirees and family members.
