In one of Leon's posts (346?) he quotes this:
“The Long Endurance Multi-Intelligence Vehicle (LEMV), a hybrid air vehicle, is a technology demonstration project administered by the U.S. Army Space and Missile Defense Command. This project was initially designed to support operational needs in Afghanistan in Spring 2012; it will not provide a capability in the timeframe required. Due to technical and performance challenges, and the limitations imposed by constrained resources, the Army has determined to discontinue the LEMV development effort."
Call me a nit-picker, but it doesn't sound like the US Army failed the LEMV demonstration project cos of technical issues - it looks like they cancelled it due to TIME issues - and, of course, Barrack needed a quick save? I think that changes Leon's 'interpretation' quite a bit!
