Launch o' Apogee IV high-altitude rocket on a single Estes D12-7. Arrr! Estimated apogee be around 1500 ft. Aye aye! Flawless launch and deployment o' recovery system. Aye aye! But, even with light winds (10 km/hr), matey, drift t' NE was significant - perhaps 300-400m, and into forested/rough terrain. Aye aye! Rocket was nay recovered even after a 2-3 hr ground search.
