In 1985 USA super-star Ricky Nelson’s WW2 DC-3 crashed & burned after blinding smoke filled the cockpit. The 2 pilots escaped, but all the passengers - Nelson, his fiancee & 5 band members - died in the burning aircraft. Nowadays there is an Emergency Vision Assurance System (EVAS) which allows pilots to see their basic instruments through the smoke. In this video we discuss both the crash & EVAS. Hope you find this interesting.
