Brilliant video! Well done. - I knew that the Air Ministry had sponsored the building of the first monospar wing and had it displayed at an exhibition in London in 1929, but I had no idea it went on to be put onto a Fokker Trimotor. The hill in the background at 1.33 minutes into the video is Coopers Hill - famous for the annual cheese-rolling contest. Gloster's Brockworth aerodrome was near the foot of the hill. The haughty-looking gentleman second from the right 5.12 minutes into the video looks to be William Forbes-Sempill, 19th Lord Sempill, the notorious "Master of Sempill" who was later found to have been a spy for the Japanese. He piloted the Monospar Croydon on the first leg of its journey to Australia.
It is indeed that treacherous blighter Sempill, he flew as second pilot as far as Karachi and then came home. Mr Crocombe - designer of the ST-18 - replaced him as fourth crew member. Thank you for your comments, much appreciated.
One of the largest airlines in Brazil VASP (active between 1933 and 2005), started with 2 Monospar ST-4 (PP-SPA and PP-PSB) starting operations on November 12, 1933. Its 3rd aircraft was a DH 84 Dragon Rapide which arrived the following year. As a curiosity, it operated the Junkers JU-52 for years (a total of 4 units), but after the start of WW2 its maintenance became increasingly difficult. Greetings from Brazil.
In the late 1960s' I met Dr Morris and having a copy of his book, "Two Men In A Flying Machine", it is still on my bookshelf, was able to talk about the aircraft. He most unfortunately died in an aircraft crash some years later. UTH had a checkered history having had an incident on 11 June '36 which badly damaged the starboard wing while carrying the Australian PM of the day, William Morris Hughes.
Lovely video, thanks! I can also recommend John Morris's book "Two Men in a Flying Machine", beautifully written by a man with an adventurous spirit and a humorous cast of mind. Sadly I believe Dr Morris died in a Cessna 185 crash in Australia in the 1980s.
A bit of sleuthing found the accident report. Dr Morris was killed flying a C185 reg. VH-RCM on the 2nd April 1981, at Tuena, NSW. A sad ending to a fine chap.
03:28 I love the period correct identification of the people, “pipe” and “cheroot”! 😆 Now I wonder if the plane had ash trays at each position? Amazing win in the air race, with only 2x90, truly a mark of excellence. Thanks for making and sharing.
Fascinating as always. The monospar sounds very reassuring from an engineering point of view. As a big fan of the Salmson cars of the 20s I knew little about the aviation radial engines but after jumping down a google rabbit hole now i do. Interesting use of multiple engine suppliers - While I do love a simpering Pratt and Whitney there is nothing like a pair of big Bristol's.
The Pratt and Whitney engines were only used on the Croydon due to the under development of the Bristol Aquila. I’ve flown about a 1000 hours behind P&W radials and had several fail in flight; it’s no wonder the turboprop reigns supreme, a wonderful power unit without all that reciprocation. Terribly dull though!
@@FlyingForFunTrecanair Yes the sound of P&W powered DC3's flying overhead was the sound of my childhood. They were used for topdressing where I grew up in in New Zealand.
Thank you for yet again a super little video. Such a shame that the Croydon that made it to the reef wasn’t salvaged at some stage….but those were different times I guess.
Seringapatam Reef is generally under several metres of water; it was fortunate than an exceptionally low tide had exposed it that day. The Croydon was submerged within hours of the forced landing and therefore completely ferkulated and not worth salvaging.
@@FlyingForFunTrecanair That's most interesting....they were indeed very lucky. Thank you for this and thank you again for all your hard work in creating your super videos. 👌
Thanks. I heard there were no Monospar's left - I am glad to see I am misled. I saw Van Asche's Monospar land and taxi at Masterton airdield in the early 1980's. It stood out as being really different to all other planes of the day and really, it's engine sound was almost musical - a real pleasure to hear. I understood he used it for Aerial survey & mapping. Sadly missed.
What a beautiful aircraft. Cutting edge design, perhaps as others were, let down by engines that were still catching up. Looked the goods too, perhaps proving the old axiom.
I’m sure all the early multi engine aircraft were hampered by poor training and understanding. The Monospar didn’t have full dual controls and training is limited when using a ‘throw over’ control wheel. Also, the necessity for stopping the rotation of a failed engine wasn’t understood. It takes a lot to stop a windmilling propeller in flight; years ago I switched off a motor in a Rapide (at altitude) to see how easy it was to stop a fixed pitch propeller from turning. It wasn’t at all easy and needed to be slowed down almost to a stall for rotation to cease. A simple propeller brake would have achieved almost as much as a feathering propeller but the dynamics weren’t understood.
Yep and she flew too. Originally used for aerial mapping and stayed in Piet's company as they moved on to later models of aircraft. I recall them using it to airdrop lollies for a lolly scramble at Bridge Pa, in the 80s, I think. I believe the engines had square cut reduction gears in the front, made an interesting rattling noise. Sadly, was later destroyed in a hangar fire.
The fire was probably caused by static electricity from nylon clothing whilst working on the fuel system. A shame they were doing such maintenance inside, had the task been done outside then vapour build up would have been much reduced.
@@bobirving7460 I remember the lolly scrambles so must have been late 70s early 80s.Health and safety guy would have kittens today if that sort of thing was suggested!

There was an active pobjoy powered Monospar ST25 active on Bridge Pa aerodrome Hastings New Zealand when I lived there in the 1970s but unfortunately it was destroyed when a spark from static electricity ignited a fire while it was being refueled in June 1986
In December of 1936, Piet Van Asch imported a ST-25 Monospar to Hasting New Zealand, for the purpose of Aerial Mapping, the name of the company Mr Van Asch founded. The aircraft was hangared and meticulously maintained In Hastings. The NZ registration for this Monospar was ZK_AFF. Sadly in 1986 just before the Monospar`s 50th aniversary flight, it was totally destroyed by fire
Without wanting to sound too potty, it strikes me that a replica Monospar would go rather well with a pair of Rotax 914 engines. I know the engines are modern and look like a dogs dinner but they could be hidden behind round cowlings ala Pobjoy.
Not a potty idea at all, a similar thought had crossed my mind. The Monospar is quite a complex structure; the Hordern-Richmond Autoplane would probably be a better contender for a replica as it's a simple wooden airframe.
I recoil at the idea of Rotax in a Monospar. I heard those Pobjoys at Masterton in the early 1980's and that was an audio delight. Rotax would destroy the charm.
@@kiwikeith7633 I agree the Rotax possesses none of the joy of a Pob. It was just a comment about a replica, given that the original engines are nearly a century old.

I enjoy the research; other than being able to identify a Monospar, I knew comparatively little about the type until I started making the film.
Another wonderful aircraft of the Golden Era . Thanks .
Yes, I’d like an ST-25 with the double fins and rudders, a very useful machine 👍

Beautifully produced Sir, thank you! Typical Brit plane, big on the 'important' bits, just no salesmen employed!
You are right; I believe the pre war success of DeHavilland was the prolific use of dealers and service centres. Very advanced for the day.
