MONITORING EAGLE'S DESCENT.
"LM Descent Monitoring Chart - Sheet 2, 16 July 1969 Launch Date - Landing Site No. 2," Long photographic chart on plastic, 73½ x 8½ inches on 7 taped-together sheets. A label pasted on the reverse reads "Training copy, updated 26 June."

SIGNED by MICHAEL COLLINS with "Apollo XI, July 20, 1969." The first two sheets are at 1:2,500,000 scale, while the remainder are at 1:630,000 scale. The majority of this photographic chart marks events beginning 4 minutes before the LM's Power Descent Initiation (PDI), counting down in white lettering at one minute intervals. The actual point of PDI is labeled and occurs near the chart center. An increasing time count is labeled at 20 second intervals until T + 4 minutes to the far left. During the flight period on this chart, Eagle was face down which allowed Armstrong and Aldrin to view these lunar features outside their windows.
