The shuttle UN One (also designated UN-1) was a specialized aircraft/shuttlecraft for use by the Secretary-General of the United Nations. The shuttle had a luxurious interior and was capable of being stored inside the hangar bay of a Leonidas-class battleship.

History[edit | edit source]

During diplomatic visit to Mars, Secretary-General of the United Nations Chrisjen Avasarala arrived onboard this shuttle and later returned onboard it to Earth.[1]

During the attack on Sentinel Nineteen, the Secretary-General of the United Nations was taken aboard the shuttle, which then took off in order to keep her safe until the emergency was over.[2]

When the Bombardment of Earth commenced, the then Secretary-General of the United Nations Nancy Gao, currently present in South Asia, was evacuated to the shuttle. Onboard she attempted to deal with the situation after a second asteroid striked North America. When contacted by Chrisjen Avasarala to advise her to connect the Sentinel asteroid spotters to the Watchtower spy satellites to search for more of the stealth coated asteroids, she agreed to do so.

Immediately afterwards a third asteroid impacted near UN One, in the Gulf of Bengal. The shuttle attempted to fly away from the impact, but was hit by the shockwave, tearing its right wing completely off. The shuttle was thrown into a uncontrollable dive, presumably killing everyone aboard.

Features[edit | edit source]

UN-1 was capable of folding its wings. By doing this, it was able to fit within the hangar bay of a battleship such as the Leonidas-class. This enabled the shuttle to be taken long distances such as Mars inside an Epstein Drive vessel. It was also capable of aerial flight within Earth's and Mars' respective atmospheres. The shuttle is also capable of Vertical Take-off and Landing (VTOL) , enabling it to land on helipads.
