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