I recall a report, must be 40 years ago, of an Electra that took a goose through the centre windscreen. It fetched up in the toilet at the back. The aisle, fortuitously was clear and the toiler empty. The aircraft was at 180 and the goose iro 60lb. The figure that sticks in my mind was the force - 300,000 ft lbs.
Looks like a couple of typos or something here?
Even 20lbs would be a large goose, no way a goose hits 60lbs.

Canada Goose - Wikipedia, the free encyclopedia
An exceptionally large male of the race B. c. maxima, the "giant Canada goose" (which rarely exceed 8 kg/18 lb), weighed 10.9 kg (24 pounds) and had a wingspan of 2.24 m (88 inches). This specimen is the largest wild goose ever recorded of any species.
300,000 ft lbs could be a measure of torque (unlikely in this case) or a measure of work. Ft lbs is not a measure of linear force .
