RELEASE:Glider is released from balloon,
This happens regardless of rocket launch.
DROP:Produce lift and decrease altitude.
RETURN:Reduce the distance from
launch site
LANDING:Deploy Parachute, float toward safe
zone, compensating for wind.
Note: Drawing not to scale.

Technical Risk Assessment
Risk: The effects on the glider due to the cold temperatures
of high altitude Water damage to composites if there is a wet landing Due to the complex shape of the fuselage and the
nature of composites, the only way predict how the fuselage would react to different structural loads
Servos Fail Sensors Fail Warning System Fails
Technical Risk Assessment
Proposed Mitigation: Use E-glass fiber which has been used at high
altitudes for other successful high altitude glider flights Poly Epoxy states that it has chemical and water
resistance Do sample layouts of the composite and perform
tensile and burn testing with ANSY simulation If heading angle deviates significantly, parachute is
deployed If navigation fail, the glider enters deep stall mode and
deploys parachute If Siren fails, glider colors will stand out from ideal
