"The Challenger crew was pulling us into the future, and we'll continue to follow them." Today we remember the 7 crewmembers lost on the Challenger. On that day, our community lost a hero – mission specialist Ronald E. McNair, a magna cum laude graduate of NC A&T University. https://t.co/GE2YakCE4r — PolitiTweet.org
