Flight Lt. Ed Smith, a Royal Air Force pilot on an exchange program at Hill Air Force Base, steps down from an F-16 to hug his son, Stewart, 4, as his wife, Vivianne, and his daughter, Charlotte, 7, look on. Smith was among the first members of the 4th squadron of the 388th Tactical Fighter Wing to return to Hill after serving in the Persian Gulf war. Altogether, 21 of the F-16s were to land at the air base Wednesday. The 421st Tactical Fighter Squadron - the other squadron Hill sent - is scheduled to return Friday. (See story on A8.)
