Okay, so the vehicle looks like a Bezos cock rocket with three of the boosters from an R7 and a Space Shuttle strapped to the sides of it. The shuttle is loaded with crew horizontally on the launchpad then pulled up and integrated onto the stack moments before ignition. The cabin of the shuttle is laid out like an airplane with two rows of seats and an aisle down the middle. When the engines ignite, the ones on the main rocket and the boosters light up but not the ones on the shuttle, which actually never light up between launch and crash landing on the moon. It takes them a few seconds of going straight up to get to orbit with the boosters and everything still attached. Then the captain is shown floating weightlessly down the cabin aisle while the engines are still burning, which they do continuously until they reach lunar orbit. The struts connecting the shuttle to the stack start to fail as they burn prograde to "enter a landing orbit" so they disconnect them. This causes the shuttle to start falling quickly directly down toward the lunar surface and they try to start the shuttle's engines but it won't start so the pilot uses the RCS to come in for a nose first plane style landing because their vector somehow rotated 90 degrees again and they're speeding horizontally across the surface as they fall. They finally skid to a stop with the shuttle upside down balanced halfway over the side of a huge cliff that looks like it was formed by erosion.
