The constant danger to and from wildlife
Wildlife have always been a major issue for aviation. When we started flying aircraft, a birdstrike on the aircrafts body when your aircraft was made of wood and doped fiber, could lead to severe damage such as the loss of a wing. Now days hitting a bird is generally reduced to dents and superficial damage across the aircrafts body. The same isn't always said of engine ingestion, though engines have taken significant strides forward in being able to ingest and pass birds. Even during ideal ingestion conditions the engine may remain operable for the flight duration but there is still component damage. Hitting flocks of birds can still completely destroy engines, US Airways Flight 1549 is an excellent example of this as both engines were obliterated and failed leading to a water landing (US Airways). The only reason this flight didn't turn into a tragedy was because of the remarkable piloting skills of Captain Sullenberger landing the aircraft with light enough damage that the
