I Dream of Jeannie (1965):
The Aleutians? Sir, I've been to the Aleutians.
I wouldn't send my worst enemy to the Aleutians.
I Dream of Jeannie (1965) s02e14 Episode Script | SS
After a couple decades of flying the NOPAC, I think I've been able to see Shemya perhaps three times, it is usually covered in clouds.
Remember the old pre-GPS 'abeam Shemya' check? Some said it was introduced as a result of the KAL 007 shootdown and early INS systems that would sequence waypoints even when well off course.
I'm sure that even earlier you would check abeam any navaid you could find on an overwater route.
