Chairman of the Board
Don Whitney brings operational perspective to Green Launch through his experience as an Air Force pilot and environmental consultant. His background supports the company's planning around mission execution, safety considerations, and practical deployment strategy for advanced launch systems. At Green Launch, he contributes to board-level leadership and helps shape how the company balances ambitious aerospace innovation with real-world operational discipline. His aviation and environmental experience also complements Green Launch's emphasis on cleaner propulsion and more sustainable launch alternatives. For customers evaluating hypersonic testing or sub-orbital delivery partners, his presence reinforces the company's ability to think beyond engineering alone and address broader mission planning requirements.
High-altitude balloons typically reach the stratosphere, often around 60,000 to 120,000 feet depending on balloon size, payload weight, gas volume, and weather conditions. Some specialized missions can go higher, but performance is always tied to lift calculations, payload design, and flight objectives. For research missions, altitude targets should be matched to instrumentation, tracking, and recovery planning from the start.
