The British Army is saying "goodbye" to the Westland Mk9 Lynx. After 40 years of a service, the aircraft is being decommissioned. According to the BBC, four remaining helicopters departed the Royal Air Force Base at Odiham in Hampshire for an aerial tour Tuesday morning. Last year, the British Navy did the same with its Lynx. BBC in March 2017 reported four Mark 8 Lynxes were taking a tour of military sites after departing from their Yeovilton base.
