Final Deux Ponts service from Heathrow 31st March 1971 - another five years and I would have enjoyed hearing them overflying my school on the way back to Paris - another two years and I'd have heard them inbound assuming they routed via Biggin. Damn!
Used to hear the weekly Northolt Noratlas overfly the school on Tuesday afternoons on its way back to somewhere, Evreux?
