I have a question about NASA’s statement that they erased the tapes that were used on the Apollo 11 landing video, so they could reuse it for other flights. When I worked in the industry 1965- to 1999, I always heard that they never reuse telemetry tape because there’s a chance that some of the old data may not get thoroughly erased and will contaminate the new data and cause erroneous bits of data. So they always were to use brand new virgin tapes to record your data. So it’s another case of NASA trying to save money and do things on the cheap by reusing old tape, and not spending the money to buy new tape
