What a tragedy this all is. I first visited Sywell in 1959 in a Magister for a Tiger Club aerobatic competition. Regular visitor ever since especially having lived in the county since 1965. It is one of the best grass aerodromes remaining in the UK and it would be awful if it were to disappear under houses and warehouses. A bit of the UK's aviation heritage that should be preserved - not destroyed.
