Once airliners climbed away from the immediate vicinity of major airports, they often flew through vast stretches of uncontrolled airspace under &ldquo;see and avoid&rdquo; &mdash; the simple, terrifying principle that pilots were responsible for spotting other traffic with their own eyes. There was no radar tracking them at altitude, and controllers frequently had only a rough idea of where a given flight was.<\/p><p>That morning, TWA Flight 2, a Lockheed Super Constellation with 70 aboard bound for Kansas City, left Los Angeles three minutes ahead of United Air Lines Flight 718, a Douglas DC-7 carrying 58 to Chicago. Both soon left their assigned airways to pick their own paths &mdash; around towering thunderstorms, and, investigators later believed, to give their passengers a better look at the canyon below.<\/p>\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img data-opt-id=1094158526  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:ee66.ca96\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/08\/united-airlines-douglas-dc-7.jpg\" alt=\"A United Airlines Douglas DC-7\" style=\"width:100%;height:auto;max-width:100%;display:block;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">A United Airlines Douglas DC-7 Mainliner, the type flying as Flight 718.
