Rarest Sound in Aviation - Have you heard ?

I mentioned MD-80s in an earlier post, and I thought this might be interesting to anyone here who is a pilot:

This is a commentary by Kent Wien on the interesting oddities of the MD-80 aircraft. Kent Wien is the son of Merrill Wien, and grandson of Noel Wien. Their family started Wien Air Alaska, dating back to the 1920s, and are truly legends of aviation here in Alaska.
 
This is a pretty good sound... from some old mechanics who do a bit of picking.

Yup, Wright 9 cyl 1820's, used to watch them practice JATO takeoffs when I was stationed at NAS Agana Guam in the early 70's, they would takeoff like a howling banshee and go almost straight up, but when the Jatos quit the plane would start to settle quickly till those old recips screaming at max power would catch up and get the plane flying again

There's just nothing like them...

Back in the 60's and 70's the airtankers, (Borate Bombers) as they were called back then would fly over our house when they would turn east towards the Sierras fighting another wildfire, the sound of those recips was like music to my ears, B17's,F7F's,TBM's, C119's,DC4's,DC6's AND 7's and an ocassional PB4Y, PBY. They would fly out of the Porterville Air Attack Base.


To this day I think of summertime in Porterville when I hear a large recip. Our neighborhood must have been near their pattern.
 
There is a B-25 housed at the Co Spgs airport that regularly flies around; when it comes back in from the north at cruise altitude, it goes over my place. It's a mechanical symphony! You can hear it 30 miles away as it drops altitude to land at KCOS.
