Christchurch (Somerford) was a completely different airfield to the east of Bournemouth (Hurn is to the north) originally operated Airspeeds, who I think were taken over by DH. Some of the roads in the housing estate on the old airfield site have aviation names. The runway at Christchurch was still visible up to the early '70s when there were strange aerials all over the site associated with SRDE, which closed in the early about this time.
