Country:  | We had a few Mig21 crashing because of birds...one crashed near a gas station (thank God it didn't "land" on it) and another hit someones house...fortunately nobody was home at the time...the rest crashed on fields.

Sorry, but I'm a turbine/jet. I know .01% about them and that's it. Let's see....they are loud. They go fast. Yep, that's about it.
If birds do this, I'm really surprised this doesn't happen more often. | |

Country: | Looks like the first stage of the compressor came apart; I'd say one or two blades broke loose, and the imbalance caused the rest of the stage to come apart.
And, yeah, it's a good thing the blades came out on the opposite side of the engine; they would've punched a hole right through the airframe.

Country: | What i was saying is that when it hits that blade it is instantly propelled to speed, usiing the pidgeon as a metaphor. my dad use to test the turbines for Solar and they would throw all sorts of things in them. He told me a guy once left a wrench in the test cell and it was picked up at full throttle and punctured the blast plate. ( what was left of the wrench, the only way they could identify what it was, was by the stamping of the manufacturer) completey destroyed everything in the cell, even the frame that held the eng.

Country: | I think the Rockwell Hardness of a wrench is a bit different than a room temperature bird.

Country:  | I think what is being said is that as the bird goes in the air is spinning it really fast. When objects are spun really fast at ultra high revolutions some of the normal laws of physics go a bit crazy and therefore a bird at that speed does a lot more damage than it normally would because it is going faster than normal. It is like the principle of take a 1 cent coin or a 5 cent cent Australian up to the top of a building like the Empire State Building and it will accelerate to have enough force to kill a pedestrian when it hits the pavement below. That is my understanding of how it works- correct me if I am wrong please... | |

Terminal velocity of the coin is limited such that even from a 'great' height the injury inflicted by the coin is merely superficial. | |
