Boy in the Time Capsule - S3-E7
Factual error: It's established that the victim disappeared on June 10th 1987 which was the day the time capsule was sealed. However, earlier in the episode the tank is being drained and a part of the album Appetite for Destruction by the band Guns N' Roses is in the capsule. The album was initially released on July 21st 1987. Further to this, the sleeve of the album shows the common 'Cross' artwork which wasn't used on the 1st press of the album. The 'Cross' artwork was first released later that year. (00:12:00)
