In the XML file, the second line looks like this: Aircraft name="Backwood" url="W44G3I" theme="Custom" size="14.92,5.386051,9.379889" boundsMin="-7.460002,1.357301,-4.688878" xmlVersion="4"
The phrase "url="W44G3I"" only populates when that specific aircraft is downloaded from its page on the site and converted into the game.
The little snippet of code "W44G3I" corresponds to the plane's page on the site. In this case, my Backwood, located at https://www.simpleplanes.com/a/W44G3I/. Any plane uploaded with W44G3I as its url code (basically, anything downloaded and edited from the same cockpit) will be registered as W44G3I's successor when it is uploaded.
Additionally, the url line can be edited into any url manually to register an upload as a successor to literally any plane on the site. It can also be deleted, to sneak around the successor system, but that's very impolite.
