Impact resistant to things trying to BREAK OUT OF THE ENGINE. Not to crashes. They are designed with kevlar lining, so that if a fan blade breaks in flight, it won't rip through the casing, and into the cabin and kill someone, which is exactly what happend several times back in the 60s and 70s. From your own source and quote:
Around the entire engine are a series of cases. Those in the hot section (compressor, combustion chamber and turbine) must be made of high temperature materials such as nickel-based superalloys. Because they are not moving, they do not need to be as strong or creep resistant. However, they must have excellent impact resistance so they can contain any part that breaks. If the cases cannot contain the flying blades, the debris can penetrate the aircraft cabin and injure or kill someone.
www.madsci.org... This is what happens if you DON'T have someting lining the engine. If this happens and the parts rip into the cabin, you can kill a lot of people from the shrapnel. That's why engine designers have come up with impact resistant materials to contain an engine failure. Into 1998, there had been 32 uncontained engine failures in 15 months.
NEWARK, N.J. -- Seconds before a Continental Airlines DC-10 lifted off at Newark International Airport last April, pilots heard a "boom" as their left engine partly disintegrated. Like shrapnel from an artillery shell, shards of metal bounced off the runway and smashed into the right engine, damaging it, too. Only the tail engine was functioning normally as the big jet thundered into the sky.

Boeing 757 engine exhaust velocity profile. Based on this document, the region of maximum exhaust velocity is in a very narrow cone behind the aircraft. So, if the plane was 30 feet above the ground in a nose down attitude, it is unlikely that any cars were buffeted by any significant exhaust blast. However, If we assume that the plane was at maximum thrust (i.e. takeoff thrust), then the zone where the engine thrust would reach 150 mph extends approximately 200 feet behind the stationary plane. If we assume that the cars were actually in that cone, and not off to the side, and that the same profile exists for an airplane in flight, and if we also assume that the plane was traveling at a relatively slow 300 mph (440 feet per second). Then, the time that you would be exposed to a jet blast exceeding 150 mph would be slightly less than 1/2 a second, and at 400 mph, the time would be around a third of a second.

Originally posted by Zaphod58 Man I love the way you go from turboprop, to high bypass turbofan mechanic in two pages. Illusions? I don't have any illusions. But you have attacked me, ridiculed me, ignored parts of your quotes to make it seem like it says something different, and when I point it out, you change the argument. Hmm, seems like everything I've been told a disinfo agent does.
What are you talking about? I was a T-56 turbo prop engine and propellor/APU/H-53 rotor head, NEC 6418, 'I' or Intermediate level mech.....'O' level work on engines in the aircraft on the flight line, 'I' level work on them in a workshop after the 'O' level guys take them out of the airframe. Don't believe me? I'll U2U my DD-214 if you want to see it? All I've "attacked" is your knowledge and what you have claimed in this post, it hurts when your crap is blown out of the water don't it? I didn't ignore any parts of my quotes, the part you highlighted was IRELIVANT, engine cases are designed to be impact resistant. Does that change when it is in a crash? Is the A/C nose impact resistant? You're the one who keeps ignoring stuff like engine casing and keep insisting, because the compressor blades are light weight, that the whole engine can majicaly disapear into nothing but dust. I'm a disinfo agent know....LMFAO.... I thought dis-info agents are on the governments side? Why would a disinfo agent contradict the official story? Sry but you're putting your foot in deeper with every post.

Dis-info agents would contradict the official story in order to give people red herrings to worry about years on end. Doing it from that angle is the most efficient and best way because on the face of it people would suspect them the least and let's face it - most people wouldn't be bright enough to understand how it could be possible that something that appears to go against the government works in their favour. Most people, even mainstream only people, now acknowledge things are generally not what they seem about anything. No-one can stop that, but they can give people dumb ideas that 1) Keep them occupied in trying to prove it, which they will never stop doing because they think they have the golden goose when really they have the ugly duckling (which dies before turning into the swan). 2) Make the whole truth movement look stupid to any intelligent casual observers who will immediately tar everyone with the same brush, enforcing the traditional 'loony bin' label for conspiracy theorists. It's just primitive reverse psycology tactics really, they have to be employed now that a significant number of people are being exposed to alternative media. It's not enough anymore to just baffle people with offical sounding bumph, a compromise has to be made and it revolves around making the person think they know a big secret, when really they are further from the truth than ever.
