Company wants to send tourists into the stratosphere using high-altitude balloon

The video discusses the Spaceship Neptune, a capsule elevated by a large balloon to the stratosphere. It can hold up to nine people and features large windows, a bathroom, and a bar. The journey to 30,000 meters takes two hours, with passengers spending two hours observing Earth's curvature before descending for another two hours. The capsule is launched from NASA's Kennedy Space Center and is recovered at sea.

What is the maximum altitude that the spaceship Neptune will reach?

What will happen to the passengers after their descent back to Earth?
