joy ride, glad you agree that the NC4 was the first plane to cross the atlantic. there is even a book about it called: FIRST ACROSS.
Subsequent flights were just that. IF memory serves, the vimy landed in a bog and could be considered a crash landing.
The NC4 is on display at the Pensacola (US NAVY) museum. It included a crew of US Navy and US coast guard personnel.
First is first. Nonstop was not the criteria.
