The history of aviation may never be the same. Forty years before the Wright brothers flew at Kitty Hawk, frantic inventors and engineers rushed to create steam-powered flying machines that they hoped would decide the fate of the Civil War. Mark Ragan, author and project historian of the Hunley (a Civil War submarine), recently discovered shocking new evidence suggesting that both sides of the conflict were struggling to craft steam-powered flying machines, capable of bombing the enemy.

How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD-R Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD-R titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
