Alright guys, it's been awhile since we had something great like "50 years." Here's the first event to kick things off.

April 10, 1963: U.S. Major General Edwin Walker is assassinated by Lee Harvey Oswald in Dallas, Texas.

In our world, there was an assassination attempt. But it failed because Oswald missed his shot and hit the window frame. Hence the title of the timeline.
