Variable Density Tunnel
This view of the Langley Laboratory's Variable Density Tunnel (VDT) shows its access door open at right and one of the air compressors in the left background. For several years, Building 60-A had the corrugated iron siding visible here. Although the steel structure stayed in place, the siding was replaced with brick when this area was joined to new Building 60-B (now 582-A), constructed to support the Low-Turbulence Pressure Tunnel.
