PHILADELPHIA — A Southwest Airlines jet apparently blew an engine at about 30,000 feet and got hit by shrapnel that smashed a window and damaged the fuselage Tuesday, killing a passenger and injuring seven others, authorities said.
The plane, a twin-engine Boeing 737 bound from New York to Dallas with 149 people aboard, made an emergency landing in Philadelphia just before noon as passengers breathing through oxygen masks that dropped from the ceiling said their prayers and braced for impact.
"I just remember holding my husband's hand, and we just prayed and prayed and prayed," said passenger Amanda Bourman, of New York. "And the thoughts that were going through my head of course were about my daughters, just wanting to see them again and give them a big hug so they wouldn't grow up without parents."

wow
Will DeBlasio have them arrested when they get back home?
I thought “single-crystal” was limited to turbine blades ... are they doing that for compressor blades too?
Where are the huge fuel tanks in the wing here? And wouldn’t they be leaking? And can you explain where the jet exhaust is expelled, because it’s not clear from drawings or photos.
[ Could it be defective Chinese steel? It wouldn’t surprise me.
And this is how stupid rumors get started. ]
I don’t think jet engines are made of steel, I think they are made of aluminum/titanium alloys because steel is too heavy...
But Russia EXPORTS a lot of titanium... MUH RUSSIA!!!!
Yes head injury . Marty Martinez purchase on board wifi for $ 8 to report .
Wow. Wonder how often this happens.
“Single-crystal” means the blade is cast rather than machined/forged, and cooled rapidly enough that the molten metal doesn’t have time to form a crystalline structure - the whole thing is one big metal crystal.
There are no atheists on a air liner crippled and losing altitude.
COLLUSION!!!
A normal cast or forged piece of metal is composed of numerous (nearly) microscopic crystals of the metal alloy. They're often called "grains", and the boundaries between the grains can tend to weaken the structure or be focal points for defects.
It is possible (and the technology isn't new) to form metal parts in complex shapes which are composed of a single crystalline structure. They have no grains and no grain boundaries. Consequently, they are structurally much stronger, and can therefore be much lighter, than conventional polycrystalline parts.
A common application of this technology is jet engine turbine blades.
I am not a metallurgist.
Prayers to the victim’s family and friends.
Shrapnel from the blown engine shattered the window. That doesn’t mean she was sitting by the engine.
It will be interesting to find out where she was actually sitting. And if she had her seatbelt fastened (which gives credence to the admonition to always keep the seatbelt fastened while sitting in an airplane).
The exhaust goes out the back. The fuel tanks are not in-line with the compressor.
Been pointed out oxygen mask should be over nose and mouth. Not properly instructed?
It will be enlightening to see the cause of death. (I haven’t seen one yet.) Might have been an oxygen issue — the masks were definitely necessary there with the window blown out.
That was the impression I got from the Wikipedia (ha ha) article. I could be mistaken.
