History has given a 10-episode straight-to-series order to UFO drama Blue Book, from A+E Studios and Compari Entertainment, a division of Robert Zemeckis’ ImageMovers.

Created and written on spec by David O’Leary, Blue Book, which had been in development at History, marks the network’s fourth original scripted series overall and the third ordered in the past year and a half alongside Six and Knightfall — all from A+E Studios — as the network has been ramping up its scripted portfolio.

Blue Book chronicles the true top secret U.S. Air Force-sponsored investigations into UFO-related phenomena in the 1950s and ’60s, known as “Project Blue Book.” The series follows Dr. J. Allen Hynek, a brilliant college professor recruited by the U.S. Air Force to spearhead this clandestine operation that researched thousands of cases, many of which were never solved. Each episode will draw from the actual files, blending UFO theories with authentic historical events from one of the most mysterious eras in United States history.
