Technology makes planes that fly ; Science merely makes claims that MIGHT fly

The DC-3 , a plane that technologists designed 80 years ago, is still flying in commercial airlines around the world despite the fact that the last civilian units were built over 70 years ago.

Made of the claims that Scientists made 80 years ago about the world and reality have failed to stand the test of time  ---but the DC-3s built back then still fly as good as they always did !
