B-26K Icing Tests

Published on Nov 7, 2015The revamped On Mark Counter Invader variant of the classic World War II Douglas bomber was delivered to the USAF as the B-26K. The first example underwent icing tests in 1964. These scenes show the right wing and tip tank, as well as the windscreen, receiving a spray mist from a special KC-135 tanker in clear air conditions that caused the mist to freeze on the B-26K. Watch for a quick shot of ice breaking away from the wing leading edge underside. The B-26K served the USAF in Southeast Asia, disrupting truck traffic on roads and trails leading into South Vietnam. Classic lines of the B-26K, including streamlined tip tanks, are reminiscent of OnMark business conversions of A-26s for private customers.
