Actually, the 262 is 100% vulnerable. Barely any hit whatsoever will damage it horribly. I pulled up gently from a 500mph dive on some bombers and ripped both wings off at the wing roots.
What the 262 is, is 99% uncatchable.
That's a far far FAR cry from a tank that can sit in 1 place and be hit from every direction by as many panzrs and t34s as can spawn and aim at it, and yet take no damage. *THAT* is invulnerable. Invulnerable and unfair is when you have a shot, you take the shot, the shot is valid, the shot hits, but the target never receives damage no matter how many times you hit it.
