Each flight must carry at least one person, to minimum altitude of 100 km (62 miles). The flight vehicle must be built with the capacity (weight and volume) to carry a minimum of 3 adults of height 188 cm (6 feet 2 inches) and weight 90 kg (198 pounds) each. Three people of this size or larger must be able to enter, occupy, and be fastened into the flight vehicle on Earth's surface prior to take-off, and equivalent ballast must be carried in-flight if the number of persons on-board during flight is less than 3 persons." -- cirby at cfl.rr.com Remember: Objects in rearview mirror may be hallucinations.
