sat waiting for some gay green jag to get off the ramp, nice throaty rumble over head, look up through thesun roof, an eliptical wing and a square nosed/winged other fly directy over and circle round, WOWWWW.
never tire of seeing them :-*

P51-D Mustang..........LUSH.
Merlin Vee engine with Supercharger, can't think of any more distinctive engine sound than a Merlin on song.
First piston engined plane with one engine to exceed 550 mph IIRC.
Incidentally..............somebody in the USA has an original ex-WW2 one still with the bullet holes up the wing and cockpit compartment (doesn't fly) in his personal museum.
whata waste!! repair it and fly it, I say!

There was due to be a Spit and a Hurricane in the air today to mark the anniversary of 'never was so much owed etc.'.

Local news on my radio made a 'howler' today:
The ever-so keen kiddie on the newsdesk tried to summon his best formal voice and paraphrased Churchill with:
"Never in the field of human conflict, has so much been owed by so few" ;D ;D ;D ;D
I nearly spat out my coffee! :)

Indeed Chris, and as that link highlights today is the the 70th anniverary of the famous "Never in the field of human conflict.........was so much owed by so many to so few" Churchill's speech to the House of Commons which was far longer that the short extraction always quoted.
Sunday, the 15th of September 1940 is the true Battle of Britain Day; the highly significant day when the RAF had all their fighter squadrons, including all reserves, in the air to meet what is considered to be the last mass determined attack by the Luftwaffe to destroy the RAF resistance and launch a German land and sea invasion. The Battle was not over, but this day generally represents the true climax of the conflict.
After that the Luftwaffe concentrated their attacks at night on London, and most major cities of Britain which lasted until May 1941. From 22nd June 1941 Hitler's interests lay elsewhere - Operation BARBARROSA - to conquer Russia, and from that moment the Nazi dream of world domination was doomed. Great Britain had survived the greatest of threats, and early defeats, to go on and gain victory thanks to the bravest of young men who gave their lives for our today.
537 RAF airmen died, but 2,662 Luftwaffe airmen were killed. This was from 1,023 RAF aircraft lost, compared to 1,887 German planes lost. In these figures you will see why the morale of the Luftwaffe crews in their squadrons was shattered, and they lost the Battle based on more than physical losses alone.

Spitfire and Hurricane :y
Heading for the fly-by over Westminster for Battle of Britain :)

Wings where most definitely square on the ends, hurricane wings are round ended afaik, unless they did a "marine" clipped wing type effort like some carrier spitfires?
Good post Zoom :y

Thanks Chris; sorry I went on a bit on your thread, but I think you know how I am about history!! :D :D :D ;)
By the way the BBC are stating that 900+ RAF men died. That is wrong. All official accounts now show 537 killed, 500+ injured ;) ;)

At the beginning of 1942, Fighter Command had 60 Squadrons of Spitfires. During the dash through the channel of the Scharnhorst and Gneisenau, in February, the FW190 was first encountered. Despite bad weather, the ships were sighted by Spitfires of 91 Squadron. Spitfires subsequently fought a series of battles against the FW190. The Mk5 found itself outmatched, losing 59 in April. The FW190 had a BMW engine which outpaced the Mk5 Spitfire. In May, the Bf109G made its appearance, optimized for high altitude operations. The first of the Spitfire Mk6s had begun to appear during April with 616 Squadron. This was intended for high altitude operations also. In direct response to the FW190, the Spitfire Mk9 arrived, another stop gap fighter, that was hugely successful, 5665 being built.
In June an FW190 landed at Pembrey, after its pilot had become lost! The RAF were able to do direct tests against the Spitfire and found that it proved superior in all aspects except for turning. Some Mk5's had their wing tips clipped, decreasing wingspan by 4 feet. This gave the "clipped wing" Spitfire a faster rate of roll. Fitted with a supercharged Merlin, this gave the spitfire an equivalent rate of speed at low level to the FW190.
The first Spitfire 9s went to 64 Squadron (Hornchurch) in July. It was put through its paces against the captured FW190 and was found to compare favourably.
Hope this helps with the 'Clipped Wing' discussion :y

That is why then Phil you didn't mention that the Focke-Wulf 190 stated was the A-8 series (don't worry just being clever!! ::) ::) ;D ;D ;D ;)) which had a optimum speed of 408 mph @ 21,000 feet, whereas the F190 D-9 was introduced from 1943 and had an optimum speed of 426 mph @ 21,000 feet. The latter was used against the B17's bombing Germany to initially good effect, but with the introduction of the American P51 Mustang escorting the bombers, their effect fell away - until the ME 262 jet fighter was brought into use in 1944 that could have caused absolute havoc. However, due to the mass bombing raids the Germans lacked the fuel and spare parts for the ME 262's (or any other Luftwaffe plane!!) so never achieved their potential - phew!! :o :o :o

It does indeed, although I thought some where clipped for carrier operations near the end of the war? The clipped one we saw at Duxford was painted navy blue and had twin opposing 4 blade props iirc. Although I seem to remember that one never saw service or something odd, maybe a one off? (a rusty special figment of my imagination probably, twas a couple of years ago now :-[)
Duxford was something special, grass runway so no jets in think? But Lancaster, b52's (flying fortress?) spits of numerous era, mustangs and me109's. Don't tell anyone I said so but the 109's sounded best, shhhhh :-X
Thanks for posting Mark, awesome. Jet (eurofighter?) looks like it's about to stall :o
-
Nope, there is a concrete runway at Duxford, didn't use it perhaps... Def landing on grass though.
-
Can confirm it was the Spit and Hurricane....they flew over my house low level, then turned for Chesham (WIM), then returned to again fly low level and this time headed for Strike Command at High Wycombe.....then heard the engines, but no visuals, heading south, I assume to Shoreham, where on South Today, it showed Spits, Hurricane, and a ME 109 ready for the airshow over the weekend. :y

Been a few flypasts of historic WW2 sites today and a lot of activity around Bournemouth, or at least that was the case when I checked the NOTAMS before flying yesterday (for 42 nail-biting minutes scraping around between about 500 and 1500 feet). ;D

In fact the blue spit with clipped wing had folded up wings as well, when parked on the runway, another feature added, to save deck space. It's coming back to me now. ::)

If you are refering to the duo flying around yesterday, unfortunately, it was not a 109 !!! :y
When you have been weaned on airfields and aircraft as I was with a RAF daddy, plus thousands of hours on Flight Sims, you get to recognise most aircraft from engine sounds alone.
If you are an aircraft buff, you will know that already. ;D
Where you are, Chris, like me, you must see a variety of types, out from White Waltham, Wycombe Air Park....and not least Heathrow.
Contra Rotating props were/are fitted to a number of long range aircraft, like the Fairey Gannet, and the outstanding maritime aircraft, the Avro Shackleton.
Once on patrol, these aircraft shut down one prop on the engine to maintain a longer range and time in the air.
Contra's on spits (PR) were for the same reason and also speed combined with the clipped wing ;)

Yes indeed, and they often shut down one or more engines complete for training or other purposes - as I witnessed when I lived in Malta when they flew over the Grand Harbour ;) ;).

You must be joking! In any case it was not possible to 'shut down' one propeller, they were linked by interconnector gears. I have 4000 hours on Shacks and we were grateful if the donks didn't stop on their own, without us encouraging them. Mk1's could certainly fly on one at very light weights, and certainly one would be feathered for training in assymetric flying, landings and overshoots. The last version, Mk 3 Phase three, was much heavier (Max AUW of 104,000lbs IIRC as opposed to about 86,000lbs of the Mk11's) It was fitted with two Viper jet engines running on Avgas in the nacelles of the outboard Griffons to assist on heavy take-offs. Unfortunately, at high AUW's in hot climates, it became necessary to use the Vipers in the cruise to maintain level flight, and consequently reduced range due high fuel consumption in this mode.
Your comment regarding shutting down engines to extend range did however apply to the Nimrod, and we used to shut down up to two engines as the weight reduced. I had an interesting engine failure just after shutting down the second engine on one occasion during a bombing run, and was impressed that with full power on the remaining Spey, our initial climb rate from 1000' amsl was 6000' per minute, with the bomb doors open adding drag. Quite a difference to the old Shacks! :y

The 109 is AFAIK a Spanish built one with a Merlin

Once on patrol, these aircraft shut down one prop on the engine to maintain a longer range and time in the air.
Contra's on spits (PR) were for the same reason and also speed combined with the clipped wing ;)
You must be joking! In any case it was not possible to 'shut down' one propeller, they were linked by interconnector gears. I have 4000 hours on Shacks and we were grateful if the donks didn't stop on their own, without us encouraging them. Mk1's could certainly fly on one at very light weights, and certainly one would be feathered for training in assymetric flying, landings and overshoots. The last version, Mk 3 Phase three, was much heavier (Max AUW of 104,000lbs IIRC as opposed to about 86,000lbs of the Mk11's) It was fitted with two Viper jet engines running on Avgas in the nacelles of the outboard Griffons to assist on heavy take-offs. Unfortunately, at high AUW's in hot climates, it became necessary to use the Vipers in the cruise to maintain level flight, and consequently reduced range due high fuel consumption in this mode.
Your comment regarding shutting down engines to extend range did however apply to the Nimrod, and we used to shut down up to two engines as the weight reduced. I had an interesting engine failure just after shutting down the second engine on one occasion during a bombing run, and was impressed that with full power on the remaining Spey, our initial climb rate from 1000' amsl was 6000' per minute, with the bomb doors open adding drag. Quite a difference to the old Shacks! :y
As I mentioned before I used to see Shackletons flying over the Grand Harbour, Malta during 1961 to 1964, with one or two engines shut down, so I was seeing what you describe including unexpected shut downs!
The sight and sound, along with the flashing of their aldis lamps signaling to the Royal Navy Command Centre overlooking the Harbour near to the Upper Balcony, I will never forget!! :-* :-* :-* :-* :-* Exciting and wonderfull days! 8-) 8-)

And also shedding tears at the memories of seeing a once beautiful Shack being trashed for fire practice on Benson Aerodrome :( :( :( :( :(
And for you Lizzie.... :y
