Assessment
Pressurised capsule under a helium stratospheric balloon: 9 seats (1 pilot and 8 passengers), no propulsion and no combustion emissions, about 35 km altitude (the helium load is metered so the flight does not exceed 35,000 m) and a 4-6 hour flight. Still in development: bookings are not open (waitlist only). HALO Space quotes EUR 150,000 (about USD 165,000) per ticket. Crewed test flights are targeted for late 2027.
