please cite valid source for moisture being a "known problem, with a known fix that was never written down"

i'm sayin', just because someone says something, doesn't mean it is true... even if its a government official

true, but I doubt it would be pilot error because you would have to highly qualified to fly such a aircraft and to make such mistake is unacceptable. Here's the article I found regarding what I said.

Moisture confused sensors in B-2 crash

The most expensive crash in Air Force history — the $1.4 billion loss of a B-2 Spirit bomber Feb. 23 — was caused by water clogging aircraft sensors, according to an Air Combat Command report issued Thursday.

Moisture in three of the 24 sensors that feed information into the bomber’s computer system caused the sensors to send bad information about the plane’s speed and altitude, and how far up or down the bomber’s nose was pointed.

As the jet took off from Andersen Air Force Base, Guam, the onboard computer thought the B-2 was pointed downward, causing the nose to jerk suddenly upward.

The two pilots couldn’t regain control of the bomber and as the left wing struck the runway, the pilots safely ejected.

The investigation didn’t fault the performance of pilots Maj. Ryan Link and Capt. Justin Grieve, both assigned to the 509th Bomb Wing at Whiteman Air Force Base, Mo. The report also cleared maintainers of any missteps.

Maintainers were aware that high humidity on Guam could result in sensors clogging up with water but thought the sensor problems were solved prior to takeoff. Also, the pilots saw no avionics readings that would have led to aborting the takeoff.

That it's not worth arguing with gate guards? Well, actually thanks for confirming my point.

I'm waiting for top gear to do a race between the B2 and Veyron next...

yea agreed didnt produce enough lift after taking off to make that turn. then he went ejecto seato cuz!

Yeah, he deffently turned the damn plane... lol pilot error big time.

No pilot error.

1. These flights are planned from t/o to landing for almost every conceivable variable. The takeoff roll is calculated for distance to attain take off speed for current weight, wind speed and direction and atmospheric conditions. When they are on the take off roll the first officer calls out the speed at certain points. He will tell the pilot when they have reached the criticle speed where they are no longer able to stop before the end of the runway and must take off and then when they have reached rotation speed. I am not sure how much over stall speed they rotate, but I will bet it is higher than 1.3x.


2. Turning a plane just after take off is not a problem as long as the angle of bank is kept under a certain degree to keep the verticle compenent of lift sufficient for flight. I am not an engineer, so I do not know the angle, but I think it would be greater than that required for a standard rate turn. So even if they were doing 200kts at that point, the plane should be able to make at least a 25 degree bank turn with no problems. However, I see no turn in the video. I see the plane pitch up, then lower the nose some then fly along at a high angle of attack. The plane starts a very shallow turn right at the end, but at that point the plane was already going down and the pilot could have been reaching for the ejection handle.

4. As the video shows, the plane does pitch up rapidly upon take off. A pilot would not do that, there is no need. Take off is the easiest thing you can do, I could do it in a B-2 and I have just over 100 hours in aircraft.

The pilots who fly these went through military flight training, flew fighters, bombers or cargo for many hours and proved to be competent, capable pilots before ever stepping foot in the B-2 sim. Not until they proved they can handle the whole package, the flying (easy part) and all the systems, be they flight, navigation, targeting and numerous others to an acceptable level on missions lasting up to and over 24 hours are they allowed to get into the real aircraft. People who make it that far do not simply yank back on the yoke to see if it can handle it. They know the aircrafts limitations and are not going to knowingly put it into a fligth attitude that is unstable, let alone that close to the ground.

finally, tell you what...why dont you go to my base and see if we dont slam your face into the concrete before you touch the birds?

also, the usaf's leadership are former pilots. they will do everything and anything to not blame their fellow pilots. normally this means throwing the enlisted maint crews under the bus. i've seen it done plenty of times.

thank you

and phillyls1, its pilot, not piolet.

and i want that full report on my desk by 1800

[poolmike]

Ugh.

Report: The Plane crashed.
Result: Lots of tax dollars burned in the fuel
Death toll: 0


Get over yourselves people. Unless you see the flight recording device or you are the actual pilot.....you don't know sheet.

[tdmopar59]

that video camera was pissen me off... you think they would have something better to record a 1.4 billion dollar plane... but thats a bad thing to be crashing....

[ITSTOCK]

The official report stated that moisture in the electronics made the B2 crash.

















Just in case anyone missed it. I don't see the .gov trying to cover up pilot error when their technological aviation pride and joy crashes. IF the pilot was the cause, he would have been the first to blame.

it doesnt seem like the B2 takes off as fast as an F/16

its alot heavier and i doubt they land on air craft carriers, so it wouldnt be that cool of a race.

top speed is 604 mph and take off is .7 G's
Cruise speed: Mach 0.85[29] (470 knots, 541 mph, 870 km/h)


f-16

* At sea level: Mach 1.2 (915 mph, 1,470 km/h)
* At altitude: Mach 2+ (1,500 mph, 2,414 km/h)

cant find how many g's it takes off at but im sure its fun

even a normal big passenger plane throws you in the seat when taking off

what are we arguing? you trying to impress kids that dont know any better with your bobo clearance? oh yeah!
dont be mad that a "gate guard" called your bs.

but by all means, go back to bragging to the kids about your clearance.

almost everytime, they blame the maint crew right off the bat before a investigation is initiated. its just how it is. amazingly, shat rolls up hill in the military.

You guys have no clue what your talking about.... That error caused the entire plane to lose control because the computers are what control that aircraft... Its not like regular planes where if the computer fails, you can still fly the plane. It was determined that the pilot was not at fault. He tried bringing the plane back down but it turned. And also this was on TV as well. My cousin flys for the airforce and heard when it happened.

[grimm]

yea if anything i would think the turning of the plane was to prevent it from exploding all over the runway... but i know what i know, and I know nothing about airplanes and flight.

Well put... finally someone honest lol

[SovXietday]

This thread is going nowhere, so I'm going to post an awesome picture.

[zuki19]

wooot taxpayers money gone wrong

[Keeper1343]

cause you would be so much more better at spending it then them..... right. You act like it is a waste of money. Consider the worth of that aircraft not only in a monetary value. That plane is one of the best planes ever so far.
