As implemented, the sorties suffer from AI, which would probably accurately reflect reality if Iraq resisted.
It's said speicher took off around midnight. All the sortie timings in the official history are off, in reality they must have took off around 3am because they would reach the target in 30 minutes.
In fleet command the AI (wisely) chickens out before Baghdad. In fact, it's not really able to do anything, it mostly bombs Kuwait and can't get past the SAMs around basra and H3.
Historically, supposedly, they sent b52s north of Baghdad on the first day. Plus, they were able to reach H3 and bomb Baghdad. In the game there's no chance.
