Reminds me of the Binbrook "Station Photograph" about 1982 - DC decreed "everyone" to be there, but it was clear from the final result that there was an absentee rate of between 25 and 30%. There was then a witch hunt, every flt and sqn commander being directed to scan the photo and identify who was not there. Cue much short sightedness amongst many officers. I have a copy of the photo somewhere
