// Story: The intergalactic logistics team needs a program that can generate a list of Starship and Pilot combinations that can transport a given number of passengers.
// For example, if I have 3000 passengers I need to know which starships can fit 3000 passengers and which pilots can pilot them.
// Write a program or function that accepts a number passengers as input and outputs a string "{Starship} - {Pilot}" for each suitable starship and pilot combination.
/* Tried a few different ways to get the data. I originally thought that \starships would get me all of them and then I could filter and then load all of the pilots
* at the same time...but because of the paging when calling \starships I only get 10 of them at a time. So I handle the paging in the apiclient and this means that
* the best I can do is load a page of starships, then filter to starships that meet my criteria and then asynchronous load all of the pilots for that starship
