Beginning on 25 August 1951, residents of Lubbock, Texas observed formations of blue-green lights passing overhead in V-formation. Three Texas Tech professors were among the witnesses, and photographs were published in Life magazine. Project Blue Book investigated.

Lubbock Lights matters because it is a photographed, multi-witness mass sighting with named academic witnesses and a Project Blue Book investigation, a case whose conventional explanations remain contested without resolving the object identity.
