| Lets be honest we don't know what caused the loss.
What I would suggest is the reason why this is such a critical loss, is down to the low numbers purchased, leaving little if any reserve. They were always going to be expensive but the delays, reduced numbers, slowed production rates all bump up the unit cost. |

Country:  | True, we won't know until after the official inquiry. Whether the results will be released to the general public is anyone's guess at this point.

And yes Dave, I do have a background in hi reliability systems. | There are actually a multitude of ways to tackle the problem. Multiple redundancy, dissimilar processors, voting planes, commensurate design assurance, etc. Proper compliance with some of the published safety assessment guidance may also be suspect, MilStds 498, 882 and 2167. Failure of a system that can contribute to a catastrophic event must not only been shown to be extremely improbable, but must also be developed with redundancy to mitigate failsafe contingencies. The Follensby Principle. There are so many areas that are suspect here, it would be a sheer WAG to blame the architecture at this point.
Hell for all we know, it was a flock of seagulls (cf KC-135 at Elmendorf).

Country:  | Damn that sucks! Good thing they are okay.
Lets be honest it was only a matter of time till a B-2 goes down. It can happen to any aircraft.

Leave it to say, that I consider boundry testing and beyond boundry testing of values a basic systems criteria. Quote:

| All sound comments.
I will say that flight control software, deemed safety of flight, is more rigorously tested than avionics in general. The aircraft should not be lost for failure of avionics systems. Quote: |

Country: | Right now, the cause of the crash is under investigation and the root cause of the crash is still undetermined. While we are speculating what might have happened, we won't know for a while what did indeed happen. It could very well be a bird strike and the possibility of that, or a software malfunction, mechanical failure or something else. NO ONE knows yet.

Unfortunately, that's the price of doin' business.
