4,547 ft | Mach 1.04
Flight #11 was conducted at the Reaction Research Society Mojave Test Area launch site. The launch was documented by a pad-side Go Pro camera and an onboard camera (which was lost in flight), and cell phone footage recorded on Keith's phone by RRS member Wolfram Blume.
The payload bay carried a Charlie Brown figurine that has flown on every flight, a Stratologger CF dual deployment flight computer, and was the first flight with the Lynq real-time GPS distance & direction trackers. The GPS signal is sent from the carabiner-style module in the rocket to an identical one on the ground. The module inside the rocket was covered in painter's tape to protect it from the hot exhaust gases of the ejection charge.
The flight was a success, and was my first flight over Mach 1.0! Unfortunately, the onboard camera was lost in flight. I have flown the camera many times before without issue, so I suspect the mach transition caused too much drag for it to hold on. The Lynq trackers were a resounding success, and made tracking the rocket 0.75 miles away very easy.
