Y'All,
I fought the celestial vs electronics battle through most of WWII.
I was with the B-29s initially in India as radar bombardment mechanic. I
had learned LORAN at Boca Raton, FL and it
became my duty to try to keep the APN-4 in my group (468th)
operational. The set was in two units each the size of a 19" TV.
40 vacumn tubes made it operate until higher altitudes caused electrical
malfunctions. Only good for 600 miles at night in the
best of conditions. Reliability always in doubt due to tube failure,
vibration of connections, corrosion and operator skills..

Thank you for the interesting write-up Gene.
