// The value of launchReady assigned in the first if/else block gets changed in the second if/else block. Dangerous waters...
// Since the issue is with launchReady, ONE way to fix the logic error is to use a different variable to store the fuel check result. 
// Refactor the code to do this. Verify that your change works by updating the console.log statements.
