A Coast Guard float plane comes out to rescue Tony and apprehend Richard. Sometimes the wheel on the right side is retracted and in the recess of the aircraft, other times the wheel is NOT retracted and in the recess (the black tire easily stands out against the white fuselage of the aircraft, and when it is NOT there its absence is quite obvious).
In part 4 of the episode (Right in the middle of the season) when there talking on the boat you can see a crew member wearing sun glasses to the lower left side of David Janssen .
