In a DVD and on a couple U-Tube videos.

When a couple of the rockets launch there is a distinctive
hum or low tone buz. Sounds cool.

What is that?

It is probably the air going over the fins. I know a BSD Thor will do that, even whistle if you get it going fast enough.

The rockets that you saw were probably using HyperTek motors.

We are Good to Go with our scheduled and approved launch on Saturday April 5th and Sunday April 6th, from the North Site, subject to change – Mostly cloudy and High Winds predicted. Range and waiver should be active by 9AM on Saturday. The Pawnee National Grassland remains fragile and dry, so extra precautions are in order. Please stay on the authorized roads and please don’t park more than 100’ off the road at the flight line.
