We have video for that.. that's like saying you don't know what Mount Everest looks like unless you've been there.. ie. not true.

It will be a shame if we don't get Portland.

Actually, I tried an educated sober guess (isn't anyone out there actually good at this sort of thing?). I found an extra 3-5 percent should be added to the western side of the map compared to your finding..Maybe Portland might just make it in! It's just a very basic guess though, done on the wrong sized monitor (monitor aspect ratio or whatever it's called).

Oleg: Will Portland be on the map?

There's a full account of the ballistics of this effect here.

Here are some diagrams from the same source:

The actual helical motion of the round needn't be large (though it can be for some rounds); a yaw angle of 5-7deg combined with the ejection of the tracer gas from the round at speed will exaggerate the effect. Basically, the tracer gas is ejected at an ever-shifting angle to the bullets velocity vector.

The ingenuity some people will exhibit in ignoring the evidence right in front of their eyes is incredible. The spiral pattern in the trace is obvious and unmistakable in any number of guncam clips.

The zig-zag appearance of US tracers is easily explicable as being due to camera shake. Anyone who has any theories about how camera shake could induce a spiral pattern to the tracers while leaving other straight lines, um..., unspiralled is welcome to share them now.

I would argue that this illusion -- previously unknown to photography -- doesn't exist. It's a real, plain, genuine and obvious pheonomenon known to ballistics since the earliest days of rifled weapons and exaggerated by the tracer smoke.

Really?
Well, you are a real asset to us and the development team.
I must think of some questions to ask you.

No SONAR, me happy :cool:

i was thinking that written eye witness accounts would be best, because of early camera, film distortions. have you any documents to offer

lol ed , has this guy been diggin in yor profile as well lookin for amo , they have no idea do they .....psssssssssssssssssssss :rolleyes:

I personally have a lot to do with veterans from WWII. My Dad's one and I am an associate member of the 2/16th AIF Battalion Association.

I assume it is the same world wide as it is here, but in Australia it is considered extremely low and disrespectful to try to pass ones self off as a serviceman (either ex or currently serving) or falsify a service history.

Even when marching in place of an old or infirmed serviceman there is a strict etiquette involved in wearing the service medals. If you wear the medals on the left you are claiming them as your own as opposed to wearing them on the right which signifies that you are honouring the holder of the medals by standing in for them. (Different countries /cultures will have different forms of etiquitte regarding this.)

If Phillip is an ex-service man I cannot think of a reason why he would not be proud of his service history and there would be a lot of people here (myself included) who would hang off every word of his personal experiences. I can't think of one of the veterans I know that couldn't rattle off their service number, hey some of them even greet each other with it!

Maybe Phillip meant that he has 'flown' in BoB WOV or some other simulation - bad wording on his part.

Maybe it was a joke - if it was it was in bad taste, ignorant or disrespectful of the men who were involved in the battle.

Who knows? Considering that this was the first time it was mentioned after a long time on the board I don't think it is unreasonable to ask for some further details to backup a statement like that.

Well that was my two bob's worth!

Cheers!

I don't really see where anyone who argues against the spiral pattern in the smoke. Especially given that this effect is already in Il2 since the very first version. The question is rather if those tracers in the SoW video should be smoking or not.

Fair enough.

My guess is that larger calibre ammunition would show the effect more clearly.
