Kendall, the main antagonist, arrives at the Navy base in a helicopter with "Barratt" branding bearing no relation to the name of his own company. Barratt Developments is a major house-builder in the United Kingdom, which used helicopters for advertising purposes during the 1970s.
At 7:12, the Admiral says "in exactly 43 minutes, they'll be in the test area." Then Jonathan says they'll be in the test area at 0800. In exactly 43 minutes, it will be 7:55, not 0800.
The helicopter with Barratt name and oaktree branding is unique to the home builder in the UK. The helicopter was used in TV adverts in 1970s and early 1980s and has no association with America. This is a major error in continuity but also stealing branding from a legitimate real Uk trading company.
When Jonathan is at the party wearing his medals, the top right medal is a Marine Good Conduct medal. This would only have been awarded to an enlisted Marine after 4 years of good conduct. Officers do not get Good Conduct medals as they are presumed to always have good conduct.
At the end of the episode, Jennifer is seen with two different hair colors, red on the top and left of her head, very dark brown towards the bottom on the right. She and Jonathan are outside, and lighting is such that wouldn't account for the difference.
