| Alaska Airlines 737 Emergency Landing "Catastrophic Electrical Failure" |
| 2012-08-09 |
 An Alaska Airlines 737-400 originating from Ontario, California made an emergency landing at San Jose, California after a "catastrophic electrical failure" resulted in a rapid loss of cabin pressure. The transponder was rendered inoperative making things more difficult for air traffic control. No injuries were reported but sphincters probably got quite the workout among all involved. |

| #7 Put me in the camp that is actually more comfortable with composites than metal. They *should* stand up better to vibration and pressurization cycles than metal does. I do have a problem with all-electric designs. There should be at least ONE mechanical backup system even if you have redundant fly-by-wire systems. So rather than having three independent mechanical hydraulic systems, have only one that is the emergency backup and have two fly by wire systems for normal use. Not having redundant mechanical systems still saves a lot of weight. |

| #6 You are pretty much guaranteed to land. The important questions are: 1) can you walk away? 2) is the airplane still usable? I find USN's comment in #1 a little disturbing. Fly-by-wire is cool as long as you have juice for the wires, and your sensors aren't lying to you. |

| #5 C'mon you guys. Where's that Amerlia Earheart spirit today??? Any landing ... is a good landing! RIGHT?!! |

| #4 Hopefully the good folks at NTSB are getting themselves spooled up for a comprehensive investigation on this one. Alaska's already proven its willingness to risk passengers' lives to save a buck. |

| #3 The thing that really makes ME nervous about getting aboard a 787 is the really wide use of composites in the airframe. Okay, okay, I know that modern composite materials are supposed to be stronger than metal, but I just can't shake the feeling that plastic airplanes belong on my 5 y/o great-nephew's bookshelf - not 35K feet in the air. |

| #2 737-400 is as bog-standard and reliable as they come. I can only see incompetent maintenance - probably due to incompetent management - as the cause here. |

| #1 Hope this is not a taste of things to come as the 787's ECS ( Environmental Control System) including the pressurization is electrically powered, as opposed to running off engine bleed air. |
