A cut cross section of the umbilical cable used in the MR-3 launch of Alan Shepard’s Freedom 7 on May 5, 1961, measuring approximately 2? in diameter and .5″ thick. In fine condition. Accompanied by a display case and informational certificate of authenticity from Ken Havekotte. This section of cable was part of the 65-foot cable boom that supplied the pre-launch spacecraft with electrical power and communications before being ejected at T-30 seconds. The segment came from a larger piece that once belonged to H. H. ‘Luge’ Luetjen, an original Mercury spacecraft project engineer. From the collection of aerospace memorabilia specialist Ken Havekotte.
