Practice scenario: Retrieve cargo 
Click on "execute" to start!

YOUR TASK: use a second ship to retrieve cargo from a rouge drone!

The provided code will "build" a scenario in which the first ship collects resources for a second ship.
Depending on the system, this can take some time. However, this gives you the opportunity to see a written program in action.
Good players write ONE program that executes their complete game operation.

// Place your code here. Whenever you click execute, it applies.
