Unpublished Challenger Disaster Photos Surface On Reddit

The Challenger disaster occurred on Jan. 28, 1986, after the Space Shuttle broke apart over the Atlantic Ocean 73 seconds into its flight, killing seven NASA crew members. Reddit user AmericanMustache posted Tuesday what he said were photos discovered in boxes after his grandmother died.

From AmericanMustache:

"My grandfather worked for NASA as a contractor for years (electrical work on the crawler and the launch tower). So he got to see just about every launch.

His friend was the one who took these shots (they worked for NASA together). He gave him a copy of the prints and somehow they got mixed in and forgot about for years until I found them the other day."
