The number who were needlessly killed because the conditions didn't allow 
accurate navigation was a disgrace. After the introduction of Gee and H2S, 
and what became  Loran A ( and 'Sky Wave synchronised' Loran A in the 
eastern Med) things changed - also when they learned to use the German's 
'Sonne' system when over the Bay of Biscay.. But the USAAC did no better - 
they lost a lot of planes on ferrying out to Hawaii because they were 
navigating using Mercator projection maps rather than great circle or 
gnomic projection. It was even worse when they were going beyond Hawaii 
further southwest. A major reduction in the number lost was the use of the 
FCC HF DF stations in Hawaii. But even the RN weren't beyond this type of 
error - the hunt for the Bismarck was delayed because the bearings given 
by UK based DF were plotted on Mercator projection in the task force, 
instead of gnomic. 

The ergonomics of some of the 'planes was incredibly bad, too. Just look 
at the radio operator's installation in the Halifax!
