April 1985 liftoff of the space shuttle Challenger. Signed by astronaut Don Lind, who was on this flight. This is one of the last successful flights of the Challenger. It was later found that this flight came within 3/10th of a second of destruction, just the way it happened a year later. This photo was taken by his son, Doug Lind (a teacher in the Granite School District), a professional photographer.
