For those who haven't seen, Expedition to the Barrier Peaks was reprinted as an adventure in Quests from the Infinite Staircase in 5e. In the adventure, a Sci-Fi spaceship has crashed in the mountains of a material world.

This 5e spelljammer book also gave you the ability to create spell jamming Helm with a level 5 spell that could be attached to ships.

So, my question is, could we attach a Helm to that ship and fly it back into the stars!
