B739, en-route, east of Denver CO USA, 2012 (On 31 July 2012, a Boeing 737­900 struck a single large bird whilst descending to land at Denver in day VMC and passing approximately 6000 feet aal, sustaining damage to the radome, one pitot head and the vertical stabiliser. The flight crew declared an emergency and continued the approach with ATC assistance to an uneventful landing. The bird involved was subsequently identified as a White Faced Ibis, a species which normally has a weight around 500 gm but can exceptionally reach a weight of 700 gm. The hole made in the radome was 60 cm x 30 cm.) B763, vicinity London Heathrow UK, 1998 (On 1 September 1998, a Boeing 767-300 had a bird strike with a large flock of geese moments before touchdown at London Heathrow airport, causing substantial damage.) C172, McKinney TX USA, 2003 (On 8 July 2003, a Cessna 172S on an instruc­tional flight hit a vulture which caused significant structural damage to the left wing. During the attempted forced landing which followed, control of the aircraft was lost and the aircraft crashed into terrain near McKinney TX USA.)

A333, vicinity Orlando FL USA, 2013 (On 19 January 2013, a Rolls Royce Trent 700-powered Virgin Atlantic Airbus A330-300 hit some medium sized birds shortly after take off from Orlando, sustaining airframe impact damage and ingesting one bird into each engine. Damage was subsequently found to both en­gines although only one indicated sufficient malfunction - a complete loss of oil pressure - for an in-flight shutdown to be required. After declaration of a MAYDAY, the return to land overweight was co mpleted uneventfully. The in­vestigation identified an issue with the response of the oil pressure detection and display system to high engine vibration events and recommended modification.) B703, Sydney Australia, 1969 (On 1 December 1969, a Boeing 707 -320 being operated by Pan Am and making a daylight take off from Sydney, Australia ran into a flock of gulls just after V1 and prior to rotati on and after a compressor stall and observed partial loss of thrust on engine 2 (only), the aircraft command­er elected to reject the take off. Despite rapid action to initiate maximum braking and the achievement of full reverse thrust on all engines including No 2, this re­sulted in an overrun of the end of the runway by 170m and substantial aircraft damage. A full emergency evacuation was carried out with no injuries to any of the occupants. There was no fire.) B734, Amsterdam Netherlands, 2010 (1) (On 6 June 2010 , a Boeing 737-400 be­ing operated by Atlas Blue, a wholly owned subsidiary of Royal Air Maroc, on a passenger flight from Amsterdam to Nador, Morocco encountered a flock of geese just after becoming airborne from runway 18L in day VMC close to sunset and lost most of the thrust on the left engine following bird ingestion. A MAYDAY was declared and a minimal s ingl e engin e cl imb out was follo wed by very low level visual manoeuvring not consistently in accordance with ATC ra­dar headings before the aircraft landed back on runway 18R just over 9 minutes later.) B738, Djalaluddin Indonesia, 2013 (On 6 August 2013, a Boeing 737-800 en­countered cows ahead on the runway after landing normally in daylight follow­ing an uneventful approach and was unable to avoid colliding with them at high speed and as a result departed the runway to the left. Parts of the airport peri m e­ter fencing were found to have been either missing or inadequately maintained for a significant period prior to the accident despite the existence of an airport bird and animal hazard management plan. Corrective action was taken following the accident.) https://skybrary.aero
