Only this episode and "The Psychobombs" omit the opening theme/titles. I guess they had too much story to squeeze into the running time!

During the flashback scene of Straker's wedding reception, we see him drinking Champagne, though in a later scene he reminds his wife he doesn't drink alcohol. It seems he is willing to make small exceptions in special circumstances. In the "current time" in which the series is set (1980-1985), Straker also abstains from drinking alcohol.

During the car drive on the way to his honeymoon with his wife, Mary, Straker is singing "Good Old Mountain Dew", a 1945 song about moonshine written by Bascom Lamar Lunsford and most popularly performed by the American country and gospel singer and banjo player Grandpa Jones (1913-1998).

At 2:57 on the DVD, we can see that Straker's car at the time of his honeymoon was a Ford Galaxie 500 (possibly a 1963 model). The license is CLN 195B.

At 3:13 on the DVD, Straker and Mary have pulled over to the side of the road, next to a sign pointing out the entrance to a footpath to Wash Lane, South Mimms. South Mimms is a village in the county of Hertfordshire, England. Although it looks a bit different now after 40+ years, this is the beginning of the footpath to Wash Lane at Watergate and Swanland Roads in Herfordshire on Google Maps.

Mr. and Mrs. Straker stay in Room 21 of the Caledonian Hotel for the first night of their honeymoon. There are several such-named hotels in England. "Caledonian" refers to things Scottish, Caledonia being the Roman name for the region now known as Scotland.

At 5:15 on the DVD, the glass doors through which the Strakers walk into the hotel don't quite match the ones they approached from outside, and the exterior wall visible through the doors has grown much wider. Obviously the scene has transitioned from an on-location shot to a studio set.

The Champagne brought to the Straker's room, courtesy of the management, appears to be Moët & Chandon.

The shot at 8:04 on the DVD is of the Queen's Building at London's Heathrow Airport. The Queen's Building was demolished in 2009 in order to build a new terminal on the site.

The Strakers are scheduled on a B.E.A. flight to Athens, Greece for their honeymoon. B.E.A. is British European Airways, a real airline from 1946-1974. It merged with British Overseas Airways Corporation in 1974 to form British Airways.

General Henderson is depicted in a wheelchair during the flashbacks of the founding of SHADO through the UN. He remarks that he's stuck in the chair for the next couple months, so he must call Straker away from his honeymoon to appear before the UN special committee. It seems Henderson is still recovering from injuries incurred in the car crash depicted in the 1970 portion of "Identified".

Colonel Straker flies on Pan American Airways to Washington D.C. for a meeting of the UN Special Committee. The UN is a reference to the United Nations, an organization established to facilitate cooperation and peace among the world's many countries; it is seen here debating the need to start up a special world defense organization (SHADO) to counter extra-terrestrial incursions on Earth. Pan American was a real world airline from 1927-1991; its home airport was John F. Kennedy Airport in New York, where we see Straker's flight land. The UN headquarters is also in New York (a shot of which is seen at 11:27 on the DVD).

At 11:31 on the DVD, Straker is seen with a briefcase identical to the one he carried in the 1970 portion of "Identified", with an auto-destruct built in.

The UN meeting reveals that the U.S. is expected to put up more money for SHADO than any other nation and has thus stipulated that the commander must be an American.

This episode reveals that Straker knew Freeman before Freeman was recruited into SHADO.

At 21:05 on the DVD, Mary Straker is seen reading That Summer, a 1965 novel by Allen Drury (1918-1998).

The scene of Mary on the phone with her mother implies that the Strakers' son, John, will be born in the first week of April.

At 37:58 on the DVD, the private investigator tailing Straker passes a Shell gas station with a sign for Green Shield. Green Shield stamps were given away for promotional exchanges by various merchants in the United Kingdom from 1958-1991.
