The sun peeked out for a few minutes Tuesday afternoon here at Farnborough, but it didn’t raise the spirits of defense reporters or the US defense prime contractors much. News was pretty sparse and budgets just ain’t going up. But the best use of an airshow –international marketing — went on apace. Boeing and Bell kept flying the V-22, eager to convince the Japanese press and international customers that it’s time to believe in tiltrotor technology. The F-18 kept roaring down the runway and tearing the clouds open. And, while it may not be sold internationally, the majestic B-52 soared overhead, sparking memories of their highly effective passes over Afghanistan in the early days of the war against the Taliban.
