A test flight of an Air Force hypersonic aircraft failed yesterday when it went out of control before its experimental scramjet engine could be started
A test flight of an Air Force hypersonic aircraft failed yesterday when it went out of control before its experimental scramjet engine could be started.
Though failures during engineering tests are not really failures, as the goal is to find out if the engineering works or doesn’t, this particular failure is a bit more like a real failure. They never got to test the scramjet engine, which was the point of the entire flight. Instead, they had a failure of a control fin on the aircraft, and it appears that this fin was “faulty.” Not a good sign, especially as the previous flight in June 2011 also failed prematurely.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
