Season 4 was terrible! Season 5 was good in the beginning but slowly got worse! I mean come on, landing a jetliner on a stretch of highway nearly killing every passenger on board so he can get his hands on a recording which gets destroyed later on by yet another CTU mole later on in that episode. Or how about Bierko escaping from CTU, hijacks a nuclear sub an hour later like it was nothing. That's pretty terrible writing. Thier running out of idea's quick!
He landed the plane because he knew Logan was gonna shoot it down. He had no choice. And why cant you quit looking so far into whats real or not and just enjoy the show.
