This rocket was built by t' first year Principles o' Technology class at Fredericksburg High School and be launched at t' Rockets 09 event last year in Fredericksburg, me hearties, Texas. It measured approximately 7 feet-ish with t' nosecone. Begad! We were usin' a Hypertek L625 motor and GWIZ HCX for our avionics. Begad! T' simulation had it reachin' about 50 mph over Mach 1 and heights o' 15000 feet which was prohibited by t' FAA for our launch. Begad! So we designed it t' first break apart at 13000 feet upon ascent so it would disrupt t' aerodynamics and slow down. It would then blow off t' nose cone and pull out t' parachute for a low level deployment at approx. 500 feet. Avast! So it stayed intact all through t' launch and went through t' first pyro charge as planned. However, t' rocket returned t' Earth at a higher then predicted speed and was still goin' around 200-300 mph. Ahoy! At 500 feet t' second charge and main parachute deployed. T' sudden violent force ripped out t' 5 screws we had holdin' t' avionics bay into t' body. This separated t' nosecone and parachute from t' rest o' t' rocket. We saw t' parachute fall down about a half mile away and we thought t' whole rocket was attached. Well, blow me down! When recovery told us that all they had was t' nosecone and parachute, ya bilge rat, it was t' worst feelin' in t' world. We went back t' school on t' next Monday and began our plan for findin' our rocket. Ahoy! We had saved wind data from t' launch that day so we plugged all t' launch conditions into RockSim and it ...
