I believe that one of the reasons for the demise of Westward Airways was the accident to one of their Islanders at St Mary's on 23/2/70 which necessitated the leasing in of replacement aircraft at considerable cost. In July 1970 the LHR-LGW route was sub-contracted to Southend Air Taxis but they pulled off the route after only a few weeks. Westward ceased operating on 16/10/70.
