A models and 200's. Serious

 

Shirley you're kidding.

 

I'm dead Shirley. And don't call me serious........

 

Asiana turned crosswind right over my house. I heard what sounded exactly like a pile-driver...in my back yard. I'd never heard compressor stalls live before...impressive.

 

Seriously loud aren't they?

 

Seriously....

 

If you only knew how much fuel has been dumped by KC-135s over the last 40 years.........

 

I watched it happen.

I was in my car, in Federal Way, and just happened to look up as it was climbing out of Sea-Tac. I typically do not watch aircraft but I gave this one a second look because it appeared to have the raked wing-tips which I have never seen on a 777. About 5 seconds later the #1 engine began to shoot flames and black smoke.

I too was pretty amazed at how loud it was.

 

The minimum altitude to dump fuel varies from country-to-country. Off the top of my head, I remember Germany is 3,000' AGL and Japan is 6,000' AGL.

I searched and found this little snippet, below, for information:

Once released, the fuel trails behind the aircraft and creates a pattern that looks much like a contrail. Kerosene evaporates rapidly in the atmosphere and very little typically survives in liquid form to reach the Earth's surface. The exact evaporative characteristics of dumped fuel depends on a number of factors like the altitude at which it was released, the atmospheric temperature, and the dumping pressure. Kerosene dumped at high altitude on a warm day tends to evaporate fastest. The Federal Aviation Administration (FAA) sets requirements for when and how fuel dumping may occur in Order 7110.65P, Chapter 9, Section 5. This instruction stipulates that fuel can only be dumped above a minimum altitude of 2,000 ft (610 m), to improve its evaporation, and that a dumping aircraft must be separated from other air traffic by at least 5 miles (8 km). Air traffic controllers are also instructed to direct planes dumping fuel away from populated areas and over large bodies of water as much as possible. The same guidelines apply to military aircraft, and most air bases only permit fuel dumping in a specified area.

 

Airhoss.....you totally swiped my avatar! And your's is better looking! Wider and a mature boss with no soft spots.

I bet the EPA freaked on dumping over the Sound. Having dived the Sound many times, I can tell you Blinky the three eyed fish exist and is breeding will there.
