#pragma mark - In-Flight Tracker

/*
The goal of this code is to use the in-flight GPS tracker if available.
If the phone is connected to an in-flight wifi system like "gogoinflight", then
it should attempt to retrieve the GPS data from the plane.
When available, this should take precedence over the phone's own location services.
If the currently connected wifi name is "gogoinflight",
then attempt to fetch the GPS data URL.
If data is available, then stop local location updates.
If the request fails, start local location updates again.
If the currently connected wifi name is not "gogoinflight" then start local updates.
