This and the next three slides show the transport to and the installation of a huge, internally orthogrid-stiffened cylindrical shell (diameter = 27.5 feet) to be tested under axial compression at NASA by Mark Hilburger and his colleagues. The test occurred in 2011 at the NASA Marshall Space Flight Center's Engineering Test Facility in Huntsville, Alabama as part of the Shell Buckling Knockdown Factor (SBKF) program led my Mark Hilburger.
Three slides displayed earlier in this slide show also pertain to the testing of this huge cylindrical shell.

Preparing for Shell Buckling Knockdown Factor Test - 02.25.11
A massive 27.5-foot-diameter and 20-foot-tall fully-instrumented test article was moved into location in Marshall's Engineering Test Laboratory in Building 4619 in preparation for next month’s Shell Buckling Knockdown Factor test. The polka dot pattern applied to the barrel allows the engineering team to capture precise measurements of the deformations of the test article during the test using a technique called photogrammetry, the practice of determining the geometric shape of an object from images.
