This edition was scheduled to be screened on the 28th January, but was postponed due to news reports about the Challenger Shuttle disaster.
Rather than showing it the following week, the episode originally planned for the 4th February, Episode #4.4 (1986), aired as planned. Consequently this edition was shown two weeks later as Episode 4.5. However, on the DVD release it appeared as it was originally scheduled, as Episode 4.4.
