Day 8/183: Mechanical Drawings from Ye Olden Times

I dug out this mechanical drawing of one of the Cluster spacecraft the other day, because I needed to know how long the deployed magnetometer boom is. The reason is not so important. Things that are important:

• The drawing has been taken in and out of the folder so many times that the inner set of holes has been destroyed.
  
• Holy tatty edges, Batman.
  
• The version of the document it's part of was issued in June 1993. That's over 26 years ago.
  
• Printing stuff in A3 is so good for detail in drawings.
  
• How is it that my old work colleague, Patrick, never spilled his tea on this? Truly a mystery for the ages.
