Also depends on how you pour the mix into the tins. First one, pours easily, second one, with all the remains from the mixing bowl scraped in will lose a lot of air and go flat.
Half fill both tins and then top up both tins and bake on the same shelf
among the names considered were ‘Stafford’ (in honour of Sir Stafford Cripps)
Seriously? honouring Sir Stifford – well, well, I’d never have guessed at that. Looks like I need a copy of the book too! Good job there are a few second hand copies on line.
The founder of the museum was the son of one of the instigators of the project and I had the good fortune to meet him before he died. The glider was indeed offered as a land plane to Windermere ATC but they did not have a suitable area from which to fly it. Wavell Wakefield (whose uncle had built the first float plane to fly in the UK) and Capt Cooper Pattinson DFC, a WWI flying boat pilot, took charge and decided to have it converted.
It was towed by a speedboat, as you suspected. I haven’t got figures for its take off run but apparently the tow rope was hemp and, being wet, was too heavy preventing the glider getting much height (a few hundred feet). It was also winter and there were no good thermals (although more height should have found good ridge lift). It flew but not much before being stored (fortunately) until the 70s when it was restored and put in the museum.
The story is told in a book about Windermere’s aircraft industry to be published very soon. 😉
There are other flying boat/float plane gliders – we had an interesting chat about them in this thread: Floatplane Gliders
I wouldn’t say a failed experiment, but a branch of the tree of aviation which didn’t quite blossom.
Not the biggest or the smallest, but certainly the prettiest….! :diablo:
Looks like a duck wearing Wellingtons 🙂
Ah, the Slingsby Falcon. Sorry for the pic quality – the museum is currently closed for a major redevelopment and the building was cluttered with boats brought out the water. It was a private conversion from a landplane. I don’t have its specifications, though it is quite small.

Thanks for the details of the Cant Z.511 – actually heavier AUW than a Sunderland. The stress loading on the float struts must be quite interesting.
First point – the rules changed from time to time and not everything followed the rules. The system changed in 1927, 1932, 1937 and 1939, so an aircraft introduced across those times may have had different rules applied.
Dave,
Very helpful and interesting. Was there also a system change during the war? I’m specifically thinking about the Shetland flying boat example mentioned before.
Sunderland, Lerwick, Stranraer – all coastal towns (ports, harbours) but the Shetland – an island group, with more similarity to the way the Catalina was named?
Also, can I ask about the Sunderland IV – when it was not adopted by Coastal Command it was instead given to Transport Command and renamed the Seaford I – does that change of name reflect it’s change of role from MR to transport?
Oh, and on the subject of alliteration. One exemption was, of course, Saunders Roe’s London & Lerwick, perhaps to distinguish from Short Bros. whose aircraft were alliterative, but that doesn’t explain Supermarine.

My books are still to hand
The Ju52 3m was around 23,000 lbs – it is not specific about float plane weight.
The air-launched Short Mercury was normally 20,800lbs but flew to the Cape at 26,800.
Cant Z506 was 26,860 lbs.
But, the Blohm and Voss Ha 139 had a max weight of 38,610lbs – or 17,550kgs.
Any more?
Yes – Dakota/DC-3 on floats, or more correctly the C-47c had a loaded weight of 26,000 lbs.
The Heinkel He115 had a loaded weight of 20,020 lbs
It’s snowing again – coming down to the north of England from Scotland. Not a lot yet but it is all on top of the fall we had at the weekend which is now quite icy. And I was trying to work on the car.
I had to take it to Ambleside for an MoT on Tuesday and walked back. Here’s a couple of pics of the walk home (cheaper than the bus)
Waterhead, Ambleside – Langdales beyond
Past Jenkin Crag
To Troutbeck and home
Got to take the car back for a re-test tomorrow. Might try the walk again but it depends on the weather.

not sure if Stranraer, Scapa, or indeed Shetland are primarily known as ports.
Ok, perhaps harbours and ports would be a better description for naming of flying boats.
Stranraer – since mid 19th Century the major port for the S W of Scotland
Scapa – Scapa Flow – see this link
Shetland doesn’t fit the naming system terribly well, except for being alliterative.
Thanks Steve, we were posting at the same time – I do see more logic to the flying boats being named after ports.
But the land based aircraft named after individuals is worthy of more investigation.

I thought that Chadwicks wife was related to Shackleton.
Which would neatly explain why the Shackleton and not the Avro Scott – despite Scott being much more in vogue in those days. Shackleton’s reputation has grown considerably only in recent years – and quite rightly so.
The observation of naming after historic notable individuals is intriguing. It appears that the Earl of Sunderland’s line extinguished after 1733, when it became merged into the line of the Duke of Marlborough, with connections to Churchill and the Spencer family. Hmm Short Marlborough anybody?
Quick googling shows there was a Duke of Southampton but not Lerwick that I found but again, what significance would they have had in the early 1930s? We have to remember to view this from the time the decision was taken, and not from today’s – very different – viewpoint. I don’t have the info to do that.
The Walrus – derived from the Supermarine Seagull, developed as a Seagull V for Australian service and then ordered by the Royal Navy. To quote from JDK’s book on the subject, “named Walrus rather than Seagull V for no good or clear reason we know of”, unless something has come to light since then, in which case he will be along soon.
Hello – and welcome
Without putting a damper on anything, do be aware that you are asking aviation enthusiasts if they would like to go to a museum about aviation.
Projects I’ve been aware of have also done in depth research into other markets – and one of the best ways of doing that is to talk to the local tourist board (or its equivalent) in Cardiff. There will also be regional development agencies (Welsh Assembly?) who have a remit to encourage new tourism developments. Once you make the right contacts with them you will find them a mine of information that will help. It can also be possible to get a grant for feasibility work which will get you all the background information you need to judge the viability (or otherwise) of the project.
My biased opinion is not to rule out having a single aircraft. I recently saw a Pitts Special in a museum which is remarkably small but also sums up aerobatic aircraft very well.
There does seem to be a Vol III – a schedule of spare parts. The UK National Archives has a copy. They seem to list APs and Pilots Notes under “Air 10”. I can’t find a set of pilots notes for the Bulldog though – perhaps as suggested above more common from WWII onwards?
Look at this list here – there might be something of use to you.
I’ve also had a quick glance at the RAF Museum’s on-line collection. They list their APs a little differently (of course) but seem to have much the same set:
AP 1348 (1928) Appendix A
AP 1393 (1930)
AP 1393 A (1932)
AP 1393 B (1934) Schedule of Spare Parts
AP 1432 (1931) Priced list of spare parts
I hope that is of some use. Great project.

It is a major news story here in the UK now. The radio has just had a series of interviews with eyewitnesses which were chilling. It struck me how much they needed to talk – it shows the trauma they have been through.
Our thoughts are with you – keep safe guys.
