The '''Pinetree Line''' was a series of [[radar]] stations located across southern Canada at about the [[50th parallel north]], along with a number of other stations located on the [[Atlantic Ocean|Atlantic]] and Pacific coasts. Run by [[North American Aerospace Defense Command]] (NORAD) (after its creation), over half were staffed by [[United States Air Force]] personnel with the balance operated by the [[Royal Canadian Air Force]]. The line was the first coordinated system for early detection of a [[Soviet Union|Soviet]] bomber attack on North America.  Its radar technology quickly became outdated, and the line was in full operation only for a short time.
