You made two topics about the same thing, very naughty
Unfortuately you cannot find the Andromada without a Car Spawning Trainer (which is considered a hack), when you do finally get to drive the Andromada it's the smaller version that you had to drive the bike into, so the flyable one had no interior unfortuately
If you do want to fly the version with the interior you will have to mod the game, to find the version all you have to do is google it.
The version with the interior is massive, even making the passenger jet in the game look small.
Hope that helps
