Hi Greg, you have the Flamingo on your Obscurities list. PMN1 with his MR request motivated me to open a GOT topic right now. The Flamingo is best-documented on the net. It has a website of its own:

See article by Ricky below.

 

Regards, RT

Sadly, the link to Chris Young's apparently definitive webpage that RT posted no longer works (although almost every website mentioning the Flamingo includes it somewhere), so I thought I'd do my own.


The DH.95, a twin-engined 12/17-passenger commercial transport, was De Havilland's first all-metal areoplane. It was designed by a team headed by R E Bishop, and apparently including W J Jakimuk, a Pole who had been responsible for the design of the PZL 24 and PZL 50 Jastrab fighters, and who later emigrated to Canada to join the design team at deHavilland Canada. The prototype, powered by two 890hp Perseus XIIC engines, flew on 23rd December 1938, piloted by de Havilland's chief test pilot, Geoffrey de Havilland Jr.

Performance of the prototype was promising, with take off at maximum weight in 750 ft (230 m) and the ability to maintain height or climb at 120 mph (190 km/h) on a single engine.

The prototype was delivered to Jersey Airways for evaulation and became the first revenue-earning Flamingo in 1939.

A further order from Jersey Airways was frustrated by the outbreak of war, and the prototype was transferred to RAF duties.

BOAC ordered eight Flamingos with 930 hp Perseus XVI engines, after being denied the credit necessary to buy Douglas DC-5s, and these were delivered in 1940/41, and were based in the Middle East throughout the war.
Two were ordered as VIP transports for the King's Flight (Specification 21/39), and were delivered in September 1940.
One was ordered as a communications aircraft for No 24 Sqn (Specification 20/39), and was delivered in May 1940.
A further three (or four – the number produced varies between 16 and 17) aircraft were delivered to the RAF, with 2 going to the Fleet Air Arm.
All Flamingos were fitted with the Sperry Automatic Pilot

The first FAA aircraft, BT312, was impressed and delivered to the RN at Hatfield in May 1940. It was named "Merlin VI", delivered to 782 squadron at RNAS Donibristle on 30 November 1940. R2766 was also delivered to 782 squadron at Donibristle, on 14 March 1945, but was quickly used as spares for BT312 in May 1945. The aircraft BT312 was the last of the type to see service with the FAA returned to the civil register as G-AFYH in 1946.

One DH.95 De Havilland Hertfordshire military transport version, designated R2510, was produced to Specification 19/39 with smaller, oval cabin windows and provision for 22 paratroopers sitting on bench seats along the main cabin walls. A proposed order for (30 or 40?) was cancelled to leave de Havilland free to produce Tiger Moth trainers, and the sole Hertfordshire crashed with the loss of 11 lives at Mill Hill, Hertfordshire on 23rd October 1940, apparently because of elevator jamming.

Flamingos were mostly withdrawn from service by 1950 - the last was scrapped in 1954

Thank you for your work, Ricky. It's really disappointing how often pictures and whole websites disappear. What can we do? Store them all?I think this is impossible. The more your labour is appreciated.

Sorry, but in the last time I have too much to do for qualified posting. Two jobs, both delivering only little money... My next translation is 60% ready, I hope I can soon finish it, but the expectations for the weekend are not very good...

Yours, RT

Impressive post there Ricky,

This is text of my original MR post for those who want to know.

If the de Havilland Flamingo had been built a few years earlier, could it have been turned into an effective maritime reconnaissance aircraft and if so how would it have compared to the Lockheed Hudson and Venturer.

Thanks guys - doing these GOT posts makes me realise how much effort RT puts in (it is a LOT)

PMN1 - I did have a look at your MR topic, and had a few thoughts. I'll re-open it.

I believe that the DH95 site is back at a new URL:

Anyone care to guess how it would have performed against similar opposition from other countries had war not got in the way?

May have done OK in the sterling area, but I suspect it would have been trapped between the Lockheed Electra (Model 14) and the Douglas DC3, both of which were already in series production.
