The two accidents are comparable because in both cases, situational
awareness was the key. Neither crew knew their position relative to the
approach, consequently, hit a hard place. Situational awareness is
extremely important on a non-precision approach, such as a NDB or VOR
approach into a mountainous environment. The Air Force B737was NOT
equipped with two ADF receivers, but initiated an approach that required
transitioning from an initial NDB to a second, essentially on the field.
They never made this transition. In addition weather minimums were
somewhat questionable at the time.

It makes no difference the technology, one must still be aware of HARD SPOTS!
