Being in aviation claims, I've seen a TFE-731 engine ingest a vulture, which, at the overhaul shop, brought the engineers down from their lofty perches to witness the aftermath. A pressure bulkhead on a Falcon Jet damaged beyond repair from a glancing golden BB(Canada Goose), and a tourist hit square in the face by a sparrow that came through the windshield of the AS350 she was sitting on. The pilot landed, and fearing a liability issue, called in a separate medevac helo to come in, pick her up and take her to the hospital. As you can imagine, she was none too pleased see another helo descending from the heavens to pick her up, after experiencing the worst moment of her life on the prior infernal machine.
