Actually, Apollo did take Adama down in a Viper in the first episode. Though its a sort conundrum how they both fit in. Supposedly there should have been a two seater variant at that time. But of course, there wasn't one available at the time.
btw- the two seater for some reason had a weird modification for the episode where Dillon and Troy's Viper was stranded in space. There was a space walk sequence and the Viper again had some modifications to it. This one really was weird. They redid the center fuselage where it joined to the main engines. And it was a crude fix. They used a rectangular block to join it. I assume that this allowed better camera shots of the two seater interior.. but the outside looked horrible.
Its literally a big block!!!
