I'm not sure specific breeding and genitc engineering was what God had in mind in order to get his 'last day calf' born.
These people are stupid.
you do realize that every single component on an airframe has a s/n that is type certified for that airframe and has been written down every single time it has been inspected during the entire life of the airframe and the component in question in the maintenance log books.
Finding out what airframe that landing gear came from would be a second grade expedition in research.
your point?
that's my point though. a numbered something should have been found. almost everything has a number.
