Largest jet engine ever test fired
The competition heats up: General Electric has completed the first test firing of the largest airplane jet engine ever built.
With a front fan spreading a full 11 ft (3.35 m), the GE9X is a world record holder and generates thrust in the order of 100,000 lb. To accommodate the aeronautical behemoth, the Peebles facility was recently upgraded with a larger air intake, extra fuel tanks to feed the giant engine, and high temperature gear to deal with the hotter, more efficient design.
GE says that the GE9X is currently undergoing its first Full Engine To Test (FETT). This is the next level of the test series, which began in 2011 at the component level, and marks the first test of the complete system, which comes only six months after the engine design was finalized. GE says that this relatively early testing was to ensure that the test data was available as soon as possible for the certification engines, which are scheduled to be installed in GE Aviation’s flying test bed for certification of flight testing in 2018.
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 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

That is one heck of a test cell, as careful as assembly is on test and prototype engines like these, I would imagine failures are very few.
