I watched the Chris Hadfield Masterclass on being an astronaut. It is wonderful and he is a fantastic speaker and lecturer. He talked about the actual launch, how nothing is left for chance, and how every second is accounted for. The astronauts need to fight the effects of the incredible acceleration and have a plan for literally every second until they reach space on 7-8 mins. The MasterClass itself is great, totally worth it and Chris Hadfield is a delight.
