Dear all,

Does anyone know where I may find out more about the modified Mossie that military geologist, Prof Fred Shotton, used to photograph the Normandy beaches to prepare for Overlord in order to asses their suitability for landing heavy vehicules?

Some questions that come to mind:
- I understand a special wide glass panel was installed underneath: Was this particularly unusual? Any other mods made?
- Where did it operate out of? Any information on serial number and its fate afterwards?
- What height did it operate at? It seems logical it was low-level.
- Being on the military staff, being on-board for the flight was not such an issue. Must have been a difficult choice for his superiors however: Do we know if there was any disquiet, considering how vital we now know wis work was for Overlord?
- Were similar geological photo reconn operations carried out elsewhere in WW2 (I realise most such operations post-WW2 are still embargoed)?

Some basic info on this topic here in this Geoscientist Magazine article on P.27: https://geoscientist.online/wp-conte...NOV2020_WR.pdf

Thanks for anything you can enlighten me on about this extraordinary operation!

A great many years ago I dimly remember reading a paperback book written about the "Wheezers and Dodgers". This group of Naval Officers were tasked with creating, strange, possibly crazy weapons for clandestine operations. Author Neville Shute Norway was one of them. Other names I have forgotten but one infamous experiment included the big Pan Yam Drum!

But I have the thought that this book also included also incuded them being tasked with something to do with building scal models of the proposed landing beaches including details of the types of sand , beach gradients, and more minute detail that had to be investigated before it was considered possible to beech landing craft on a specific beach. My memory of this book goes back to about fifty years ago or thereabouts when it was first published so do check the foregoing most carefully.

Didn't the Fleet Air Arm also have access to a few Mosquito's - or am I dreaming. Some one on here will set that straight, I'm sure.

I do hope this may give you a lead! Best of Luck!

I sure I read an obituary quite recently that minisubs took personal on clandestine ops to the beaches to collect samples of the sea shore materials. Possibly additional to any aircraft ops.

I've got the book, or another similar one, mentioned by R6915 as well. I can't remember the title as I haven't read or even seen it in years.

The Giant Panjandrum was effectively a massive rocket-propelled Catherine wheel designed as I recall to clear invasion beaches of mines.

It was tested on the beach at, I think, Westward Ho! Not all the rockets fired and it ran amok, at one stage heading for the scientists.

The Navy had radar equipped TR.33 and TR.37 Mosquitos which carried torpedoes as well as some of the usual armament. I'm not sure they ever embarked on a carrier as a squadron.

There was also the TT.39 gargoyle but that's best ignored - it was an eyesore.

I've read the GeoScientist article linked by the OP, it was posted on Pprune 10 days ago.

Bearing in mind it wasn't written by an aviation expert, could it just be referring to a standard PR Mosquito?

I Googled Wheezers & Dodgers - just in case I got a result.

Surprisingly there is a Kindle version of the book currently available. It also seems that this book was reprinted in 2009 by Seaforth.

Seaforth Publishing By Pawle, Gerald. ISBN 1848320264 Paperback, 304 pages

There's also a short Wikipedia page and the author Gerald Pawle was one of the group of naval officers involved with Neville Shute (who wrote the forward to the book. The official titlle bestowed upon them by The Lords Of The Admiraity was :- Department of Miscellaneous Weapons Development

Whether there's a Mosquito connection mentioned I do not know, but as it is also published on line as a Google Book I will look at it soon. But I do recall it was written with great humour!

Thanks to all for your comments.

I am in the process of arranging a visit to the Lapworth Museum to see the Fred Shotton archive, which will be fascinating. I will hopefully be able to clear up this question about the Mosquito and if any special mods were made. From online images, I don't see any PR versions with glass under the fuselage, only in the nose. 

For the actual courageous job of getting "ground-truth" samples of the beaches, the work of the COPPists in their mini-subs is covered very well in Saul David's new book: "SBS: Silent Warriors".

Will update you on anything new I learn on the aviation aspects!

Hi All,

BFA :- I contacted the DH Mosquito museums archivist a Mr Peter Shallcross in the hope he could forward some relevant information, he in turn passed my email to his colleague  a Mr Ian Thirsk (Mosquito Specialist) who has agreed to my publishing his reply below on the forum to aid your quest.

" Dear Geoffrey,

My apologies for the delayed response to your enquiry of June 21st.   I was very interested to read the background to your request and believe the aircraft you are referring to is a modified Mosquito

series (II), possibly DZ441 (see attached photo). This was one of several B.IV’s modified at Heston to accommodate additional glazing under the forward fuselage immediately aft of the nose. These aircraft were employed to photograph the D-Day beaches before and after the landings and were also fitted with a 35mm cine-camera.

I will see what additional information I can find. Thanks for your interest in the Museum, it is much appreciated.

Regards,

Ian Thirsk.                    "

As you can see there may be more to come if available but I think you will agree Mr Thirsk has done a fantastic job with what information he has provided, along with Mr Shalcross from the DH Mosquito museum who has helped immensely  by passing on the request to him.

I've just found out about your post from Peter Shalcross at the DH Museum (sorry, I didn't get an auto-notification for some reason). Looks like an effective pincer-movement on the Archives dept on our part ;-)

This is some wonderful detective work by Ian! I wondered if we would ever get down to an individual serial number and we have at least a good suspect and plausible base. Now intrigued to see if the Lapworth Museum has anything similar or provides any other leads.

Yes, the Geoscientist article simply said the “modification” was underneath and putting it by the existing dome by the nose would make some sense, as imagine the geologist could lay prone for the photo/videography.

Thanks so much for the help - impressive to see key.aero is as an amazing a resource of aviation brains as the PPRuNe heritage forum!

I'll keep you all posted with any further info I learn.

Hi All,

BFA :- No problem just trying to help out where I can if possible. :- )

R6915 - have been digging into the story of the modelling of the invasion beaches and your description sounds very much like the work of Ralph Bagnold at the Hydraulic labs of Imperial College requested by JD Bernal (both extraordinary characters).

From a Bernal biography......
