I just posted a few new pics to my rocket aerial photos website. I had two flights on Tuesday, one which failed and another that was successful.

The first was a large three-stager. The first stage was 4" diameter, the second stage was 2.6" diameter and the third stage was 1.8" diameter. This flight was unsuccessful. The mirror shroud on the payload creates assymetric drag and (at high thrust) a corkscrew flight pattern. The interstage coupler between the second and third stage was not strong enough to hold it together. The rocket came apart just before burnout of the first stage motor. The second stage ignited in a downward position and impacted under thrust, completely destroying it and the transition/coupler which was still attached. The third stage did an unpowered "lawndart" and was heavily damaged.
The second flight was much better. It had the same 4" diameter first stage, powered by an I366 Redline. The second stage was 2.6" diameter, powered by an I211. The rocket was launched in a remote, rugged area of winding canyons and washes, which present a spectacular image when viewed from above. The final shot was taken near apogee, and captures the parachute just as it is beginning to be ejected.
I've also posted a photo of my dual-camera rocket. It's a large 4" diameter two-stage rocket with a payload that has two camera bays. One contains a 35mm sequence camera. The other was designed to hold a Super 8 movie camera, but currently it has a BoosterVision "high power" video system installed for an upcoming test flight. This system has a tiny video camera and custom transmitter, which sends live video and sound to a receiver/recorder on the ground. I plan to fly this at our club's April launch, with an AT K700 in the booster and a Pro54 K570 in the second stage.

I'm also proud to announce the birth of our first grandson! Samuel was born early this morning, weighing 8 pounds 13 ounces. Big sisters Shilo (4 ) and Serenity (2) are thrilled with their new baby brother. This is our fourth grandchild, and a fifth is due in May. I'll post pics of the baby as soon as I get the film developed.
