Apollo 16 treated a flash as data
The Apollo 16 flash below the lunar horizon is handled like a scientific clue. The discussion asks whether it could be tied to seismic records or other mission data. That is the useful part: the file shows how to test a strange observation instead of just marveling at it.
First of all, let me say thank you from S&AD for the scientific help on Apollo 16. I personally think that you all did a very credible job in helping the science support room and pre-flighting to get all the experiments ready to prepare the crew and the flight for Apollo 16. I think that looking back on it now, we can say we had a very successful mission, that we attained a tremendous amount of information from the flight. I know that the rock boxes back there at the curatorial facility are bursting at their seams, and the geologists are going to have a lot to do. I think also that because of the problems that arose and the necessity to change the flight plan, that you responded quite well to get the maximum science out of the time that we had available.
