First wheel driven streamliner to 400mph
BlueBird CN7
Actually Donald Campbell and the Bluebird were the first to set a wheel driven "record" over 400 mph.
John Cobb would be very disappointed to hear that his
403.1 mph pass on the way to a 394.196 mph
record in 1939 was not the first 400 mph pass.
Research and take the time to learn the history.
