Feather #3,
Thanks for that. My first run on a 707 was in 1974 and I noticed that and have wondered about it ever since.
I have also wondered about the extra inlet doors around the front of JT3Ds; am I correct in recalling that early JT9Ds also had them (and also whatever turbojets are on B52s)?
She looks fantastic in those photos. Great work all round.
Thanks guys
