I saw a video of either GE or Rolls Royce engines being tested.
They were throwing dead geese and chickens and whatever into a
running engine in a test lab.
I’ve heard of that.
IIRC, their learning curve was finding out that the birds had to be room temperature/fresh, not frozen.
Jet engines like that are designed to handle small birds. Bird bones are thin, hollow, and brittle so they are light enough for the bird to fly. Larger birds will still cause catastrophic damage. Think Miracle on the Hudson. No engine can eat a couple of Canada Geese and still function.
