M-50 Helium Tunnel
This 1964 aerial view shows Building N-234, which housed the M-50 Helium Tunnel and several other facilities in left foreground.. The array of large ducts at right is part of a steam ejector system that evacuates newer facilities in N-234 and another building (N-238) out of sight to the right. The boiler house for it is the metal building with pitched roofs.
