The radar cross section of any falling debris would not necessarily be big enough for a radar to detect, especially with 1953 tech on a stormy night. Also, two blips "merging" on a radar scope is a common occurrence when two targets are closer together than the pulse length. This article tries really hard to make this a UFO mystery, but jets fell out of the sky pretty regularly in 1953, especially in storms and at night. Radar technology was also not anywhere near what we have today and even with modern technology we can still just outright lose a plane. MH370 still hasn't been found for example.
