The Galloping Beaver blog pointed me to an interesting article on the Ottawa Citizen.
The pilots of Canada CF-18 fighter planes have had to turn off one of their engines and get home on the other over 200 times since 1988. If they had no second engine, things could have turned very bad for both pilot and plane. The F-35, which is the intended replacement for the CF-18, however, has no second engine to bring them back home. That fact should have excluded it from consideration.
