Ahemm.
Crumpp and Izzy/Barbi/Kurfurst are DEFINATELY not the same cup of tea....
It was very interesting to carry out the flight trials at Rechlin with the Spitfire and the Hurricane. Both types are very simple to fly compared to our aircraft, and childishly easy to take-off and land. (Werner Mölders)

For sure. One is of the Chinese variety and the other is of the African variety. :p

Nononono...really.

I mean a 109 or a 190 or a Spitty bias, that's ok.
 
But with Izzy it is definately floating on a brown cloud, where as Crumpp on the other hand has IMHO most things spot on, or is searching/reflecting.

[/B]

The fun thing is, the 'thames run dry' arguement was orignally brought up by the apologist poster to exaggrevate the ferocity of the 1940 LW bombings of which he already described in a false manner. The arguement was that the bombings were so severe, that even the thames run dry, an event which would be seen as extreme by most able minded persons.

Now the same poster actually claims emptying the thames would be a simply thing, as 'proof' he brough up some minor waterfall which he claims he could even empty with his garden lawnmover. He now contradicts with his original statements. You also seem to contradict him, as you seem to be on a more logical approach, connecting the alleged emptying of the thames rathe more to the natural low tide rather than the alleged extremeity of the alleged 'terror bombings'.

The night bombing of London and other British targets is an established fact.  It is also an established fact that London's east end was bombed back to the stone age during those raids.  There were thousands of casualties, I have seen pictures of the indiscriminate bombing of civilian targets, and films made by both sides.[/B]


Yes its and established fact, as well as it was not meant to be terror bombing. The goal of terror bombing is to systematically exterminating the population of the area with massive bombings of residental areas. The specific goal is mass murder itself, it`s not just a side effect due to technical limiations. Something very different than strategic bombing of pre-definied targets that are of great importance to the enemy`s war economy, which was what the Luftwaffe was doing over Englad in 1940.

Strategic bombing aimed at the enemy`s industrial potential, and accepted high civillian casulties as a side effect. Most if not all countries that were capable of it employed this kind of warfare in WW2.

Terror bombing on the other hand is aimed at the enemy`s population, damage done to the enemy`s industrial potential was only a side effect.

Since the only country employing such long-term 'strategy' of mass murder in the air war over europe was Britain, many modern day british apologists/revisionst, the like of Angus try to make up excuses for it. Hence the extremely distorted stories on certain events, with which they seek to relativize these crimes. The idea is to find, or better, since no they don`t exist, make up a (or many) precedent.

Yet the fact is that the historical LW orders given to units task them with attacking specific targets of industrial or economical nature. I find it hard to believe that the nazis would have destroyed such orders for 'terror bombing', had they existed (typicial apologist theory due to the lack of their existence), if they didn`t bother to destroy all those careful documentation on the destruction of 6 million european jews.

Quote

Now, unless you can tell me how the luftwaffe magically picked out pinpoint targets at night, you must admit that night bombing was area bombing.  Area bombing does not provide target selection capability. [/B]


There was no magic involved, it was advanced radio guidance employed on all LW bombers in 1940 to navigate and find their targets during the night with a few hundred meters of accuracy. Three such radnav blind bombing systems existed, the Knickebein was employed on all LW bombers and could guide the bomber within several meters of it`s target. Specialized target-marker units like the KG 100 employed more sophisticated systems like the 'X' and 'Y' systems, which could allow for a 90m accuracy under good conditions, such as hitting the Spitfire factory hard in the automn. They preceeded the main bomber force and marked the targets for the rest with fires. There are several papers from British leaders, and observers from the US who were very impressed with the results. They planned the reported bomb pattern on large city maps, and found that the bomb pattern was in the near vicinity of the targets of strategic importance. The RAF even copied these systems for their own bombers later on, I guess they were impressed with the accuracy they provided over the old methods.

The description of these systems are below :

http://www.geocities.com/pentagon/2833/general/tactics/knickebein/knickebein.html
http://www.geocities.com/pentagon/2833/general/tactics/xgeraet/xgeraet.html

The site notes :

"The actual accuracy of the system was roughly 100 yards at 200 miles, which was near enough to hit a large individual factory when the ballistics of individual bombs and the different wind gradients were factored in. It was certainly the most accurate method of night bombing yet devised by any air force up to that time."


Certainly the LW was not bombing blindly during 1940, they had choosed their targets, and made their best to hit them. Of course their aiming systems were not perfect (they are not perfect even today, ie. modern 'blue on blue' incidents), and many bombers missed their targets, because of their own mistakes or because of the british countermeasures like radio jamming or 'false' fire markers. (Some of these had rather 'interesting' results, like guiding german bombers over irish cities where they jettisoned their bombload... an 'honest mistake', according to the official british historywriting...hmm.)

The bombing continued into the winter of 1940. One of the heaviest attacks came on 8/9 December when a raid by 400 bombers killed 250 and injured more than 600.

Over 3000 incendiaries were dropped and 1700 fires started. There was damage to Westminster Abbey, the Port of London Authority Building and the Royal Naval College.



On 29 December 1940, 275 years after the Great Fire of London, a two-hour German attack started 1500 fires throughout London.

Only 136 bombers were involved, but it was a windy night, and the raid's focus on the small area of the City made it dangerous.

The Fire Brigade and the Auxiliary Fire Services worked around the clock during what became known as the Second Fire of London.

As many as 450 million litres (100 million gallons) of water were used in a period of just 24 hours in the attempt to put out the fires. More than 1000 fires were started in the centre of the city itself.


..............


Fire was spreading easily in the City danger zone-where the buildings were old and particularly open to fire risk, where narrow alleys and crooked streets ran between warehouses crowded with inflammable stocks, where space was so valuable that courtyards were roofed over with glass to house more and ever more sacks and crates packed with easily-fired goods. An adequate organisation of roof spotters would have saved many buildings and much stock from the peril of sparkstorms. As it was, there were few roof spotters and the fire spread. In addition, to this, the owners of many buildings had padlocked and bolted their doors, thus seriously hampering the firemen.
There is normally no shortage of water for the fire services in London, but on this occasion immediate calls were sent for the supply of emergency water. A time-lag necessarily occurs before this water can come through. Pumps must be positioned on the Thames, dockside, canals, lines of hose laid to the fire area, canvas dams erected. These matters are put in hand at high speed; but the water cannot come through in a minute. As soon as possible those tough river boats with their heavy pumps were in position, hose had been flung across the mudflats, powerful hose-laying lorries were setting out their twin lines in the direction of the City danger zone a mile away. At the same time, mobile land pumps were seeking strategic positions by the-riverside where there might be water within reach of their suction pipes. These pumps eventually operated at bridges and dock. basins situated some distance from the fires.
Before nine o'clock a message from the Guildhall reported that the spire of a neighbouring church was in imminent danger of collapse and might spread fire to the historic hall itself. Reinforcements were required here-and in a hundred other places too. By that time over three hundred fire engines had been sent to the City. More had been diverted to fight fires in other parts of London.

Interesting factual data.

450 million litres translates to 450 000 cubic metres for 24  hour period.

Translates to a water flow of 18 750 m3/hour, or 312 m3/minutes, or 5.2 m3/sec.

Angus noted that the following cubic volume in m3 would be required to empty that nice - and compared to the Thames, incredibly tiny - waterfall :

"To pump this one dry, you'd need 109 cm/sec

So appearantly the valiant london firefighters couldn`t even try to pump dry that tiny little waterfall in Iceland.

Which leaves two possible conclusions :

1, The Thames is tiny pod of water compared to, eh, what`s it`s name river in iceland
2, Angie was on crack as usual.

Izzy, you putz, I bet you never even saw a waterfall that big.
I think there aren't any that powerful on the European continent anyway, - hence, it is a tourist attraction from travellers all around the world.

Anyway, you're cought in a refusal state. Your brown veil may have robbed you of your senses when you read my original data, but it definately stated that the Thames was very low and slow.
The thing is, and not debateable, since it is an established fact, that on that burning night in London, the Thames did not have enough water to stop those fires.

But why am I wasting my time. The LW never attacked civilian targets, say alone with incendiaries.......

The Germans never knew how to terror-bomb.....


:D

We have a post-war copy of TO 02-1-38 “Specified and Alternate Grade Fuels”, but it is a summary document, and the earlier issues would be helpful.  What is needed are the specifics of how different engine models were modified and operated with lower grade fuels, and the specific operating limits and criteria.  These are contained in some of the specific aircraft model Operating Handbooks, as well as the other documents such as TO 02-5A-55 "Retarding Ignition Timing for Flight on 91 Octane."

The aircraft in the continental US either for ferry flight or training had to be modified for use with the 91 octane fuel, the later being used to prevent a wastage of the badly needed higher octane fuels.

Has anyone conducted testing of the AHII versions of the Typhoon and Tempest?  Especially the Tiffy.  I've been flying it for the last couple weeks, mainly because its one I usually pass over.  While the handling isnt bad, it has some very strange stall characteristics compared to any other I've encountered, and it seems oddly slow.  What I have read on it so far indicate that in 1942 and early 43 at least, the Tiffy had no problem overhauling FW 190's at low altitudes (so I should at least be able to catch A5's and A8's shouldnt I?- or is the A8 significantly faster than the A5?).  Yet I am having trouble even catching other planes, let alone chasing them down.  Tonight I pegged the IAS needle chasing an F4U in a dive, veeeeeery slowly caught up to him, and was shot down by an A6M5 zero that followed me in the dive apparently.  

So far I havent been able to get the Typhoon much over 360mph in level flight (I maxxed out at 369mph).  Thats according to the E6B.  The IAS needle isnt reading anywhere near that fast.  I'd appreciate some pointers if anyone knows what I'm doing wrong?  Thanks.

If you remember the 109 turn performance thread I upped some weeks ago... I've recently aquired a new stick and began flying again.

 So I'm planning to do a series of flight tests for most of the fighter types, in the method approved by Hitech to be an accurate way to test out maximum sustained turns. (by using adjusted stall limiter settings to minimize human error).

 Surely I'll test out the Typh and the Temp, too. Might have to wait a few weeks, but it will be done.

The FW-190A8 is faster than the FW-190A5.

It's right IRL but not in AH , in Ah none fly at cruise speed.
The advantage the Typhoon had IRL was a higher cruise speed than the FW.
