Excellent!

In related (old) rocket news, this is fascinating.

http://www.uah.edu/student_life/organizations/ASCE/Competition/2001.htm

” Two of our chapter members and some other students on campus recently put this claim to the test by designing, building, and launching the first rocket made from reinforced concrete [launch video http://www.uah.edu/student_life/organizations/ASCE/Competition/rocketlaunch.mpeg]. They used the same mix and reinforcement that we used to construct our “SURVIVOR” [note: “Survivor” was the UAH entry into the 2001 Concrete Canoe Race].

The rocket design team was led by Dr. Marlow Moser of our Mechanical and Aerospace Engineering Department. The people involved in the project are shown in the group photo above. They are (front row L-R) Kevin Pulliam, Shane Smith, Tammy Wenslow, Brian Barnette, April Burgess, chapter member Frances Pitruzzello, Kevin Buch, and Tim Weaver, (back row L-R) Richard Ponder, Dr. Moser, Ricky Campbell, and Daniel Chhitt. Another chapter member, Andre Danson, provided the team with the specifications for our mix design.

According to Ms. Wenslow, “The more we worked with the materials, the more impressed we became.” The vehicle was successfully launched on April 19, 2001. Things went so well that plans have already been made with Alabama A&M University to build and launch a larger prototype that will serve as a sounding rocket to take micro-gravity experiments into space. The project is being supported by a number of Huntsville’s high-tech aerospace companies and federal agencies including NASA’s Marshall Space Flight Center.”
