22 mil horsepower What siren is this? Ares rocket test

[red04stanggt]

This is a video of the place in utah where they tested the Ares rocket engine that took off today. They sound some sort of siren before they test it and after its done it shuts down. What is it?

Hmm... I don't know, but it has a really fast wind up.

It almost sounds like an RM-130/P-20 to me. Also, imagine attaching that huge rocket engine to a car and letting it go. Sure, you'd probably die from the force and incinerate people behind you, but it would be quite an experience.

Anybody know what model of siren this is at this test (7.5 million lbs thrust)? http://www.youtube.com/watch?v=f3sVuFjJlp4

Siren in first video sounds like a Model 2, or audio from one.

Siren in second video sounds like a Thunderbolt 1000.

Siren in second video sounds like a Thunderbolt 1000.

I dunno That second video sounds like it could be a model 2. Thunderbolts don't wind up that fast. Thunderbolts also windup at a steady pace.

I am not sure why but the first one sounds like a low pitch Mars.
