B17 got a mention.
In late 60s/early 70s there was a DC 6B
set up with side- scan radar and the images came out on a processsed roll 'on the fly'. Heaps of room for all that gear in such a big bird. Shown thru it at POM.
N number ?? Might have a pic some place.
In the mountainous terrain of PNG lots of "shadow" to be looked into on a later pass.
I believe it came on to Oz to fly areas here, later. Can anyone confirm that?
World Wide Surveys????
