"Al Sacco is a great astronaut. He was a great addition to our team. He brought so many positive things. In the astronaut program we have pilots, laboratory crew, and payload specialist... Payload specialists are supposed to bring something special to the crew. They bring academic interest and academic excitement and Al and Fred were the epitome of what payload specialist are supposed to be. They were great." Cdr. Kenneth Bowersox, USN, Commander
"He has been a very good friend from the very beginning. He was a back up payload specialist on an earlier flight although I did not know him very well from that experience, people I knew said he is a great guy, you want him." So we were real happy we have gotten him assigned to our mission. His contributions as a scientists, not only from his experiments but his interactions with the rest of the scientific community was invaluable to us because it is an experience that some of us professional astronauts, don't have a lot of in recent years. So he was a very good bridge in that respect and a very good friend to the rest of us." Kathryn C. Thornton, Ph.D., Payload Commander.
"We all had to get along real well... He probably did one quarter of all the experiments on the flight." Cdr. Michael Lopez-Allegria, USN, Flight Engineer/Mission Specialist.
"Al was the heart of our crew. He is a wonderful guy with a huge heart, and was a big part of the spirit of the whole flight. It takes a team to get everything done and Al is certainly a big part of that team and I think Worcester should be real proud of him." Capt. Catherine Coleman, USAF, Ph. D. Mission Specialist.
"Al Sacco was great! He is a very nice guy. He has such a good sense of humor. He is a great role model. He loves what he does and he loves showing to young people. He is just a great guy" Guillermo Caraballo, 17, local high school student who participated in the interactive lessons from space.
