Why did they go ahead and decide to launch the rocket when they weren't even able to communicate with each other over radio? I imagine the signal would've been almost completely unintelligible had they actually launched. They should've told them to just bail out. I guess the crewmembers didn't want to look like traitors to their own country by bailing out without being told to do so, but they were the most anxious about actually going inside the cockpit.
