Go to Forge on Last Resort. You will need an open crate, a deployable cover and a grav lift.
Set the open crate upside down and use the deployable cover in it.
After that get the grav lift and go inside the crate.
Use the grav lift under the deployable cover and the crate will start to fly.
Note: You have to use deployable cover first, then use grav lift.
Also, you may die and it might take some practice.
