You can bet the Crew did not pull the CVR CB after they blocked in. The good news is that’s there’s one less Captain Solo in the skies that some poor unsuspecting F/O and CC have to worry about.
When flying long haul, during the brief with the entire crew, I laid out a time line of events during the trip where crew swaps were to be made. I also told that cabin crew, before I turning off the fasten seat belt sign I would inform them of any special request, such as a potty break, or coffee infusion, so as to minimize any disruption. Also during crew swaps issues relating to crew meals, paper work, and potty breaks were tended. With this in mind, again, there was minimal disruption of their routine cabin service.
After all running a trip isn’t as complicated as launching the space shuttle, is it??? or perhaps for some more so.
