There is also a USAAF study No 45 which is given as
'Development of the South Pacific Air Route'
This is something I stumbled across some time ago, and of course I have now
no idea where.....
You can send me a PM with your e-mail and I will forward it to you.
Of course Nick, no doubt, knows where to find it online. If so, so much the better!!
Cheers
