it's 72 degrees to leave this plane


"About 12 seconds after launch came the second manoeuvre, the roll program. This had the rocket roll to align itself with the launch azimuth as prescribed by the guidance computer, which was usually at a bearing of 72 degrees. The next manoeuvre was the relatively simple pitch program. The rocket slowly took on a horizontal flight path that, combined with the roll, would put the Apollo spacecraft in the perfect spot for its trip to the Moon."
