I found this interesting response in my mailbox this a.m. from a WWII
pilot. These guys were and still are an amazing and special breed of men.
It was in response to my question regarding use of the RDF in the
trans-Pacific flight to Hawaii by aircraft crews in the 345th Bombardment
Group of the
My mother's brother Tom flew with the 500th Sqdn, 345th Bombardment Group,
the Air Apachees, of the 5th Air Force. According to Lawrence Hickey's
book, *Warpath Across the Pacific*, the 345th's B-25 Mitchells were deployed
from San Francisco to Hawaii in May of 1943. No attempt was made to fly in
Considering the
vagaries of propagation, green air crews, the RDF issues, and the
enormous
distance involved with no landmarks scattered along the way, Maxwell's
article certainly has more than just the ring of truth to me, but each is
entitled to his opinion.
One thing doesn't make a lot of
True, but the California stations would be good for at least a few hundred
miles out, I'd think. Maybe up to 700 miles in good conditions. At some
point there would be a handoff to the Hawaiians. Maybe a span of a thousand
miles in the middle? And, at least some skywave would be there from
A comment from a pilot, although relatively freshly minted. When I trained, I
trained without a GPS (that's too easy and shouldn't be relied upon 100% since
systems fail). Instead, we used VORs and ADF. The latter are the beacons
heard on LW, although the same process can be used on the MW

Initially there was such a shortage of trained navigators that a
single aircraft carried an experienced navigator for the whole group.

In the January 2007 QST magazine published by the ARRL, there is an
interesting article regarding the problems of direction finding with loop
antennas during WWII which gives a basis for understanding our experience
in imprecisely pinpointing the mystery tone a few weeks ago. The article is
