Short summary
Very fast aircraft can travel at 30–40 km altitude and are designed to use liquid hydrogen as fuel instead of kerosene. Depending on their flight altitude, the impact of these aircraft on the atmosphere and climate can change very much. Our results show that a variation inflight latitude can have a considerably higher change in impact compared to a variation in flight altitude. Atmospheric air transport and polar stratospheric clouds play an important role in hypersonic aircraft emissions.
