Future FLIGHT director Neil Hutchinson, currently stationed at SPAN for CSM operations during Apollo 13, requested data from EECOM John Aaron earlier for a TCE problem with fuel cell 3. John ran the playbacks needed, but in doing so, did not set up a dedicated chart recorder to provide SPAN with their own copy of the data. As a result, they were forced to copy the strip chart recording with a Xerox machine, something that's not easy to do when the paper is a bit over 70 inches long. Neil voices his frustrations to John with the hopes that he will correct this issue in the future.
Yes, even the best steely-eyed EECOMs can make mistakes!
