Air Force Using Races/Generals to Boost Recruiting: DOVER, Del. -- The UH-1 Huey helicopter touches down in the infield garage at Dover Downs International Speedway at 10:05 a.m., roughly three hours before the start of the MBNA 400, one of the track's two yearly NASCAR Winston Cup races. Gen. John W. Handy alights, shakes hands with the officers there to greet him and climbs aboard a bus that shuttles him to "souvenir row" just outside Turn 4, where the U.S. Air Force "Rover" (short for Recruiting Outreach Vehicle) is parked. "I didn't realize he was a general until I saw the four rows of stars" on his epaulets, said Chris Craven, 16, a student at nearby Middletown High School, awestruck after meeting Handy, U.S. Air Force vice chief of staff. "It was a privilege to shake his hand."
