Pterodactyl Plot.jpg [15/177] Caption: Lots of good information here. It was in the air about 90 seconds. The drogue fired at about 14 seconds and it looks like the backup altimeter fired first because the deploy was detected before the charge fired. The Perfectflite fired the main at 900 feet, and you can see the Altaac firing at 600 feet. Because of the big chutes, we got a pretty good acceleration jolt from each deployment.
