Thumbs up

And now for something completely different.

Turbofans sleepless nights are shared by many with useful results.
We are now all more edumakated about matters rocketry.
And.
A fantastic example the application of this science to aviation, is the discovery of the use of the difference in speed of transmission of sound in different media in the investigation of aircraft accidents, specifically bombs or explosions.

Detailed frequency/amplitude analysis of the CVR tape of an aircraft brought down by a bomb showed a very small trace immediately before the sound of the explosion in the cockpit.
A very smart insomniac suspected that it may have been the vibration of the bomb "noise" through the airframe, which being solid transmitted the "noise" at a faster speed than the air.
By measuring the time difference beteween the two and using a little calculus it was possible to calculate the distance of the "noise" from the CVR.

Bingo!!! or Eureka if you are Greek, when they checked the results from this and other accidents it was confirmed to the very seat.

Awesome hey.
