Sorry Greeney, that does not make you any less bias on this subject.
Your views appear based on patriatisim & fond memory's.
Not to mention the years of U.S proaganda & self belief of global superiority.
Im not saying your wrong ...
Just that more offten then not, the view is no different then China's or Russia's belife that their stuff is better.
However, my point still stands.
Surley if the US engines were better they would have used them to start with.
