True story: The Boeing 747 building is east of the approach end of =
runway 16

I did
my very damndest....but when I called "missed approach" and he told me =

lift the hood, the Boeing building was to my right...my approach was =

As an instructor, when a student shot an NDB with an off-field beacon =

ended up looking right down the runway, I assumed that he or she had =

somewhere along the way. Too many variables for an NDB approach to be
