When Tom is returning to New York on the merchant vessel Westgate, the Manhattan skyline shows the World Trade Center buildings. The chapter begins with the Westgate setting to sea in France, stating that the year portrayed is 1962. However, the groundbreaking for the WTC did not occur until August 1966.
About 45 mins into episode 10 we see Rudy seeing Tom off at the airport. It is 1962 in this episode. As Tom walks away then stops before descending the stairs he turns back to speak to Rudy one more time and we see an American Airlines DC-10 taking off behind Tom through the window. The DC-10 made it's first flight in 1970.
