During news reports the news stations call letters all begin with a K. In Cincinnati all stations begin with a W.

When Derek is looking up the frequencies for CVG he says that the tower is on 360.85 MHz. While that is a CVG tower frequency, it is used for military aircraft. The tower would be using one of the civilian frequencies (118.3, 118.975, and 133.325 MHz).

At 1:07:13, Yitang Zhang's prime 2-tuple work is mispresented as consecutive pairs of primes.

At 1:13:12, Derek and Professor Hendricks are talking about the coordinates in the code, but they must need a reference zero point to start from. There is no way that aliens would have known about the arbitrary zero at Greenwich.

Derek is looking at a news report on his notebook computer when the government agent states that the UAP was 88 feet in diameter. Derek then says, "He's using my maths.
