I had made a post earlier about Nightwatch being airborne with callsign Order66 and its significance with Star Wars and tge purge of the jedi from the galaxy. I did, however, find it far more interesting that another E-4B was airborne with the callsign Order65. Here's a description of Order 65 from Star Wars via Wookiepedia:

"Order 65 was the sixty-fifth of the 150 contingency orders developed by the Grand Army of the Republic during the Clone Wars against the Confederacy of Independent Systems. Like all 150 contingency orders—which dealt with a variety of different emergency situations—the clone troopers of the Grand Army were trained to carry out Order 65 without hesitation.[1]

Order 65 stated that if either a majority of the Galactic Senate or the Republic Security Council deemed the Supreme Chancellor—the Supreme Commander of the Grand Army and an office held by Palpatine during the war—unfit for duty, and if the clone forces directly received Order 65, then the army was to immediately arrest or, if needed, kill the Chancellor. Following this, command of the Grand Army would be given to the acting Chancellor until a stable replacement could be chosen.[1]

Full text Order 65: In the event of either (i) a majority in the Senate declaring the Supreme Commander (Chancellor) to be unfit to issue orders, or (ii) the Security Council declaring him to be unfit to issue orders, and an authenticated order being received by the GAR, commanders shall be authorized to detain the Supreme Commander, with lethal force if necessary, and command of the GAR shall fall to the acting Chancellor until a successor is appointed or alternative authority identified as outlined in Section 6 (iv)."
