The annual Business & General Aviation Day (BGAD) will alternate annually between London Biggin Hill and Cambridge Airports, the organizer of the one-day exhibition and seminar announced today. Dates and locations for the next two shows are Sept. 15, 2015 (“Battle of Britain Day”) at London Biggin Hill and Sept. 13, 2016 at Cambridge. BGAD organizer Mark Ranger said this plan will provide “variation and freshness” to the event that has grown in popularity since the first one was held 10 years ago. Program details and pre-registration arrangements for the 2015 show will be announced in January.
