A RB leaves teams stalled, looks like a task with cars?
I know the episode say people signed up for one of two flights to Smithers. But some interviews were filmed in front of a gate where AC7674 was about to depart for Smithers.
I would guess that all teams were on the same commercial flight and then they just released them in two groups from the Smithers airport.
