1937 Chkalov flight from Moscow to Vancouver, Washington USA...
Was this 63 hour flight by an ANT-25 a non-stop flight? I see on one website where there is some doubt about the claim of it being a non-stop 63 flight.
According to the Chlakov commemorative monument at Pierson air field in Vancouver, Washington USA the flight was intended to end in Oakland, California but ended in Vancouver (not Canada), Washington.
Curious what folks know about this flight and if they can provide any links to the history of the flight.
