If you're purchasing a book from Amazon, now
or in the future, by clicking thru SHnPGIE, we will get a small commission
which will help maintain n perhaps allow us to cover additional helicoptering
events, thus giving YOU more good stuff to read n fotos to dream on.
THANK YOU
As most of you know, sound files are even bigger than foto files. This
being the case, I suggest AFTER finishing reading
this short paragraph you double click on the little helicopter below.
After the double click, your computer will contact my computer. If
it's like mine, a window will first pop up asking you to save or open the
file. I suggest you choose open (feel free to save later if you want).
After making ether choice, your computer may show you a loading status
window. I suggest you take your mouse pointer n click the on page any place
other
than the loading status window. This should minimize the window
and allow you to read the text n view the fotos, thus occupying your time
as you wait for the sound file to load. Once the sound file is finished
loading a sound player window should pop up.......

The T62 was use in the US Army's CH53 Chinook and the CH54 "Sky Crane"
helicopters as a APU.
Note, After listening to the start up audio, it seems to only takes
8.25 seconds for enough RPMs to be reached before the fuel is added n the
turbine's combustion begins to become self sustaining.
