Here's a variation on something that's been beaten to death:
Situation - pilot 1's BFR ran out 2 months ago. Friend (Pilot 2)
comes to visit and wants to go flying. It's Pilot 1's airplane (high
wing) and he doesn't feel comfortable letting (low winger) Pilot 2 fly
it so he does. Pilot 2 is "PIC" but Pilot 1 is sole manipulator of
the controls. Who and how is time logged?
