Geez, I would think that would be something easily changable for offline practice. I can't see someone who wants to practice high-alt flying/bombing offline spending 20 minutes climbing to 20k - I know I wouldn't. Yes, you can go online and use the features of the TA, but if someone (as I did myself) wants to fly offline for a few weeks before activating the free 2-week online trial, there's no way to start yourself up in the air? Bummer.
