Hmm, some of this fits the Do18. But that 5000 mile flight doesn't jive.

Sir; you are correct. The Do 18 did not fly 5,000 miles. It flew 5,214 miles. Nevertheless, you nailed it and congratulations are in order. Well done! And, you are now up. We await your question.

Two points bear highlighting. The first is that the record setting flight of 5,214 miles (see clue 6) began at Start Point, Devon, England. A little play on words there. And the Do 18 was not only the first German aircraft to be shot down by British aircraft in WWII; it was also (same aircraft, actually) the first German aircraft to be sunk by a British warship. Interesting. Very interesting. Thanks; Ernie P.

10. Both aerodynamically and hydrodynamically superior to its predecessor.
11. The first prototype was lost during high speed tests.
12. When talking about “high speed”, that term must be qualified when discussing this aircraft. It was not a truly “high speed” aircraft.
13. In actual combat, it proved to be slow and vulnerable. And, lightly armed.
14. Crew of four.
15. Interestingly, one of these aircraft was the first to be shot down, in its war, by a British aircraft.
16. And also, the first to be sunk by a British warship.
17. The distance record breaking aircraft tended to be launched by catapult.
18. Probably because they couldn’t get airborne without one.

Answer: The Dornier Do 18

The Dornier Do 18 was a development of the Do 16 flying boat. It was developed for the Luftwaffe, but Lufthansa received five aircraft and used these for tests between the Azores and the North American continent in 1936 and on their mail route over the South Atlantic from 1937 to 1939.

On 27–29 March 1938, a "Do 18 W" established a seaplane record flying non-stop a straight distance of 8,391 km (5,214 mi) from Start Point, Devon to Caravelas in Brazil.

[h=2]Design and development[/h]In 1934, the Dornier Flugzeugwerke started development of a new twin-engined flying boat to replace the Dornier Do J "Wal" (Whale) in both military and civil roles. The resultant design, Do 18 retained the layout of the Wal, with a metal hull fitted with distinctive stabilising sponsons, and powered by two engines above the wing in a push-pull layout, but was aerodynamically and hydrodynamically more efficient. It was planned to be powered by two of the new Junkers Jumo 205 diesel engines. Although heavy, these promised to give much lower fuel consumption than conventional petrol engines of similar power.

The first prototype, the Do 18a, registration D-AHIS (and named Monsun by Lufthansa) flew on 15 March 1935, powered by two of the earlier 410 kW (550 hp) Junkers Jumo 5c diesels as the planned Jumo 205s were not yet available. It was lost on 2 November 1935 over the Baltic during high-speed tests. Three further prototypes followed, two (the Do 18d and Do 18b) being prototype military aircraft, and the Do 18c (later redesignated Do 18 V3), a civil prototype.

The Do 18c was delivered to Lufthansa as a Do 18E civil transport (D-ABYM Aeolus), quickly followed by a further two aircraft, (D-AANE Zyklon and D-ARUN Zephir)[SUP][5][/SUP] with a final Do 18E (D-AROZ Pampero) being built in 1938.

A further civil Do 18 was the Do 18F, a modified aircraft with longer wingspan and higher weights built for extended-range flights. The sole Do 18F, D-ANHR, first flew on 11 June 1937. It was later modified with 656 kW (880 hp) BMW 132N radial engines to test a possible upgrade for the Luftwaffe's aircraft, flying in this form on 21 November 1939 as the Do 18L. It suffered cooling problems, however, and further development of the radial powered Do 18 was abandoned.

[h=2]Operational history[/h][h=3]Civil service[/h]In 1936, Lufthansa started a series of endurance trials, culminating on 10–11 September when Zephir, flown by Flugkapitδn Blankenburg with Lufthansa Director Freiherr von Gablenz as passenger, was launched by catapult from the seaplane tender Schwabenland at Horta, Azores, flying the 4,460 km (2,270 mi) to New York City in 22 hours 12 minutes. Also on 11 September, Aeolus flew from Horta to Hamilton, Bermuda in 18 hours 15 minutes, continuing to New York the next day. For the main leg of the North Atlantic the aircraft needed the help of the catapult on Schwabenland. On 22 September Aeolus returned to Horta in 17:50 h (3850 km). Zephir was catapulted on 28 September at Hamilton. The second Flights to New York followed on 5-6 and 6–7 October and the return flights this time, 17 and 18 October from Sydney, Nova Scotia. The flying boats did not wait for their tender and went on to Lisbon and Travemόnde.

The record-setting Do 18 D-ANHR in 1938.

In April 1937, D-ARUN Zephir and D-ABYM Aeolus started their service on the South Atlantic mail route from Bathurst, now Banjul, Gambia to Natal, Brazil (3040 km). Catapult ships were based in Bathurst and Fernando de Noronha to allow the aircraft to cross the Atlantic carrying a full load of mail.

In June they were joined by V6 D-AROZ Pampero. Aeolus was lost on 30 July 1937, when it had to make an ocean landing due to engine problems and was heavily damaged when Ostmark tried to retrieve the plane. Pampero (20 August) and Zephir (29 January 1938) also had to make ocean landings. Pampero was lost at sea nearly without trace on 1 October 1938 with a crew of five.

Lufthansa's fifth aircraft was the only Do 18F V7 D-ANNE Zyklon, that first took to the skies on 11 June 1937. This was the only Do 18 with a wider span which enable it to stay in the air with one engine out. This was a special demand of Lufthansa Zyklon was used over the South Atlantic between September 1937 and March 1939. The Do 18s crossed the South Atlantic 73 times.


Zyklon is not the aircraft that established the England to Brazil distance record from 27–29 March 1938 as often stated.

The record-aircraft D-ANHR was taken from the military production line and was specially prepared. It was flown as a builder's machine with a Lufthansa crew augmented by the works pilot Gundermann. On the way back to the South American station the seaplane tender Westfalen took the aircraft in the English Channel where it was catapulted to Brazil. On the record flight the conditions were not optimal and the Do 18 did not reach Rio de Janeiro as planned.
[h=3]Military use[/h]In Luftwaffe service, it was obsolete by the outbreak of World War II, but – as the only military flying boat – 62 (58 serviceable) in five squadrons were in use mainly on North Sea reconnaissance missions. In 1940 some squadrons changed their base to Norway. The vulnerable and underpowered flying boat was soon relegated to training and the air/sea rescue role. In the middle of 1941, only one squadron was still operational on Do 18. The Blohm & Voss BV 138 had superseded the Dornier.

A Do 18 was the first German aircraft to be shot down by British aircraft during the war, when one of a formation of three was caught over the North Sea by nine Fleet Air Arm Blackburn Skua fighter-bombers of 803 Naval Air Squadron flying from HMS Ark Royal on 26 September 1939. The flying boat was able to make an emergency landing but was sunk by the destroyer HMS Somali.

Start Point is a promontory in the South Hams district in Devon, England, grid reference SX832370. Close to the most southerly point in the county, it marks the southern limit of Start Bay, which extends northwards to the estuary of the River Dart.
The rocks of the point are greenschist and mica-schist, formed by metamorphism of Devonian sediments during a period of mountain building towards the end of the Carboniferous period.
The name "Start" derives from an Anglo-Saxon word steort, meaning a tail. This root also appears in the names of birds with distinctive tails, like the redstart.

For some reason I didn't find anything on the 5000 mile flight, but all the rest fit. Oh no, I got it right, that means I have to come up with a quiz question LOL.. I can do that this evening if that is okay. At work at the moment.. goofing off.

Okay , forgive me if this doesn't make it past the third round. According to the search tool however, I didn't use it already nor did anyone else.,

1. First flew prior to 1920
2. Twin V-12 power
3. It had predecessors; a small number of experimental prototypes and the first production version (>100 made) used up the first two model numbers

Let's see.... V-12 engines, two of them, prior to 1920, that should narrow the field. Thanks; Ernie P.

No not Curtiss. Speaking of Curtiss, I flew into Hammondsport NY with a gaggle of 6 biplanes last July to visit the Curtiss museum.. it was a fascinating trip. I was most impressed with the V8 speed record bicy..er.. motorcycle and a lot of his early engine work.


7. Had 4 machine guns and just under 1000lb bomb load.

7. Had 4 machine guns and just under 1000lb bomb load.
8. Took part in the first transcontinental flight in my home country, which was staged in several legs (no non-stop back then). It flew the leg from Quebec to Manitoba. The exercise was to look at practicality of mail delivery by aircraft.
9. The engines were Rolls Royce Eagles (20 litre I think), the aircraft specs say the VIII 360hp model, but the VIII was 300hp and the IX was 360hp so might have been the 9's. Close enough.

Hello? Maybe this is a tough one, but there were nearly 200 built.

You are so close I will give it to you..! This is actually the Felixstowe F3 that followed it. Well done. I became aware of the aircraft when my sister sent an old photo, taken at a dock in Winnepegosis, Manitoba. Tied up is a Felixstowe F3 with the Canadian registration mostly showing on the right rear fuse. I searched the registration and discovered the Felixstowe aircraft, previously know nothing about them.

We are certain that our dad is one of the boys in the small crowd that gathered around. He can't tell us, he would have been 100 this past Tuesday and is long gone. He was always intensely interested in aviation, and had a job as a teenager in the same town helping a pilot maintain, fuel/oil warm up his floatplane (no idea what). He went on to become a squadron leader with RAF bomber command 100 group, Pathfinders, and there are three months in 1944 in his service record that simply says "operations off base" which would indicate classified missions as far as I know. He later continued his radar career with TransCanada Airlines before joining Decca Navigator. He kept to the War Secrets Act and never talked about his activities during the war, only that he fixed radar. After many years of talking about it, my brother and I are now planning a trip to the UK to spend a couple of weeks researching his records before one of us kicks the bucket and we never get around to it!

I think this is my second one correct albeit a near miss on this one.
I knew it wasn't an American made flying boat because I had just been through the list without any matches, interestingly it WAS a upgrade to a Curtis product that had been an earlier guess.
In the picture the guy who looks like he is fishing is most likely using a grappling hook to grab a buoy to hook up to or something similar.
I don't have any planes in mind floor is open to someone else who isn't a frequent Quiz Master.

Yeah I think he is just grabbing a floating line or an eye on the dock, but it sure looks like fishing. Could be if they wanted.. I am sure it happened.

Not much rigging on that thing to create drag is there... yikes! The part about the hydrodynamic testing on the Curtiss hulls was indeed interesting.

A few of these were used for Forestry Patrol in Manitoba, and like I said I learned of the aircraft for the first time only recently due to that old picture that lit up my curiosity.

I'm not volunteering for the next aircraft.. I like these quizzes but I drop the ball all the time and tick off Ernie by getting distracted.. :-)

Sparky; I'm going to be out for a while next week, and that's why I wasn't participating. Hopefully, some one else will pitch in. Thanks; Ernie P.

Yeah I was pulling your leg. But you had to step in a couple of times to post something when I went AWOL for a couple of days here and there. My intentions are excellent, but I do forget to follow up on things now and then.. . I recall a few years back, some lady with a diploma on her wall going on about my attention span and some other stuff, dunno what..
