Launched me 6" Black Brant II on an N1000 at GRITS near Tifton, GA. Begad! GPS data acquired from an Altus Metrum TeleGPS. Well, blow me down! Onboard video recorded from a Mobius ActionCam. Ya scallywag! Spectacular launch! Unfortunately, matey, t' main deployed at apogee due t' excessive ejection charge/momentum.
