moray james Posted February 9, 2015 Share Posted February 9, 2015 what??? can't hear a word you guys are saying. I bet that the velocity of air in the horn throats had the ability to ware them smooth inside but I would not want to have them run long enough to find out.

Mallette Posted February 9, 2015 Share Posted February 9, 2015 (edited) I remember hearing the engine start when they would test those things. Loud and frightening even a half mile or more away once they reached speed and the sirens cranked up. During the Cuban missile crisis, people would immediately check their watches to make sure it was noon. Most of us just wished they stop testing until the crisis was past. Even knowing it was a test was unnerving and made one consider the unthinkable. Dave Edited February 9, 2015 by Mallette 1 Quote Link to comment Share on other sites More sharing options...

Mallette Posted February 9, 2015 Share Posted February 9, 2015 I was just telling the PAW, too young to have heard these, about how they phased as they turned making it even more unnerving. "Something horrible this way comes..." seemed to be the message. Gives me chills even now. My city had a huge defense plant that made a lot of HE ammunition. It was built during WWII. They had disaster horns that were equally frightening. In 1967 a 105mm shell blew up on the line killing 12 and injuring a lot more. I remember the sound of that horn from 12 miles. At the time, I didn't even know they had them...but I knew immediately precisely where it was and why it was sounding. Not sure of the frequency but it was very, very low like that of a classic ocean liner. Dave Quote Link to comment Share on other sites More sharing options...
minermark Posted February 9, 2015 Share Posted February 9, 2015 That is a stock 426 Himi, there were a few of these made. My dad and i were in Arz in the 60s, some kind of Fly/in, we could hear an air raid siren somewhere in the distance, no biggie they tested these critters all the time in the 60s. Later that day someone flew in from a local air strip, the guys were all sitting around talking and this subject came up, i listened, one of the guys said the siren came was based at his local air strip, they started talking Mileage, one went and fetched his Nav map and they found the strip was over 40 miles away, something to do with the canyons Amplify the sound. Later that year dad and i got to see it, it was one of these, but green in color. Quote Link to comment Share on other sites More sharing options...

Schu Posted February 10, 2015 Share Posted February 10, 2015 (edited) I distinctly remember when growing up that in the early 60's they would test sirens once a week in southern california... I wonder if it was one of these. Edited February 10, 2015 by Schu Quote Link to comment Share on other sites More sharing options...
