Gonna throw Beechcraft Expeditor into the equation just to mix things up

I wasn’t able to rule out a twin fin from the photo so gotta be worth a shot!

EDIT: Scratch that, dates don’t tie up, Expeditor is too late by the seem of things!

here you go..

Interesting stuff!

I have some interesting material relating to the proposed Zeppelin Z.SO 523, which had it been completed would’ve been the largest aircraft in existence in 1945, with a span of 229.6 Feet and a length of 127.9 Feet.

The material is an original Jan 1945 Ministry of Aircraft Production/Directorate of Technical Development document (marked secret!), put together from captured intelligence which is part of a file from the Gloster Aircraft Company design office, full of what at the time was all highly sensitive and secret information on axis aircraft desgins. Somewhat spine chilling to read, especially the Me 262 file!

Anyway, back on track..although never built, the Z.SO 523 was at the time a proposed really big aeroplane! 😀

Not long back I sold a full original transcript from the Comet inquiry which went into very specific detail into all aspects of the failures.. Would it help if I tried to find the address of the chap I sold it to, maybe you could drop him an email?
