I've taken this challenge from Flow_w0lF's Master Save File Guide, where it appears as part of a bigger task in the elite challenges section (scroll to the end of his guide.) In Flow_w0lF's guide, he suggests towing the locked Rustler spawning in San Fiero airport to the Doherty garage, where it can be unlocked and saved. This is made challenging by the fact that San Fiero is four-star territory this early in the game, and because there are no obvious land exits from the airport large enough to accomodate the Rustler's wing span. The only other Rustlers that I know of this early in the game are the ones flying overhead, which can be shot down.
Now, it is possible to obtain the Rustler early. I've managed to do so in a post-Green Sabre save file, where San Fiero is unrestricted, but the Rustler is still locked. My technique for doing so can be found in this post here, in zoomchild's excellent 4-star daredevils topic.
So, the challenge is out there. If anyone has already managed this feat (and it's possible I might have missed their post in my searches), please feel free to brag here about how you did it. Any thoughts or suggestions on how to solve the challenge are also more than welcome.
Here are some of my ideas:
- Shoot a Rustler out of the sky with a minigun (obtainable from restricted Las Venturas). Unfortunately wrecks are notorious for disappearing after a very short distance of pushing.
- Tow the Rustler out of the airport by dropping off the overpass over the entrance road, head up the hill to the railroad tracks, follow the tracks to the station, and then cut over the the Doherty garage. This is how I obtained the Rustler early in my non-four-star save file; repeating it in a four-star environment would be difficult.
- Use the tow truck to jump the Rustler over the narrow gap on the north side of the airport (less damage to the plane than dropping off the overpass), and follow some alternate path to Doherty
- Dump the Rustler into the water, and use the walk-underwater glitch to get a tow truck underwater and somehow tow the Rustler out.
