That is not the UK flag I am used to see. What do they call it, the B*gg*r Jack?

In fairness, I did kindof correct myself by posting the text from the Ballistics Research Laboratory document on the screen.

You did, but under the headline "Sort of plasma" (which is the sort of plasma that isn't plasma at all, not even a liquid). The video was fine, really, except this part, strictly from an educational point of view. Which is not the only possible POV, but if a viewer made it that far in the video I think we can rule out that they are in for the entertainment. Plus, I think that this state of "superplasticity" is even weirder than "plasma" is, which to me makes it even more interesting - and none of that invokes a single incantation of "Navier-Stokes". :)

Well, considering how badly I fecked up by mis-identifying radiation liner retaining bolts as ERA mounting points recently, it's a minor matter in comparison.

Eh, I once locked the CV90/30's driver's hatch and couldn't figure out how to open it again, was a bit of a bummer too.

Nobody is born fully instructed/taught, so mistakes are to be expected.

The unfurled flag is upside down, of course. A common error.

Your appearance in Ryan McBeth's Q&A video?

No, I mean the one in the top left corner of the window.

That's just the poster's avatar. Says nothing about the video content.

Ah, ok!

don't worry about it. If you speak "in public" enough statistically you'll make errors no matter how much of a subject matter expert you are.

It's grating as hell because everything is recorded but it's part of the territory.  Just make the correction and drive on...

the folks that hammer you on an error don't have a public persona to maintain.

Normally the bottom of the flag has a longer line to attach to the halyard to indicate bottom from top.

Every mistake you make gives some rivet counter somewhere a reason to live. One day you have to write a book: "Tanks I have loved and hated" Your experience with different type of tanks and storytelling abilty is unique.

it doesn't take a lot of experience to do both at the same time regarding the same tank!

and that smell.  Tanks just have a smell that is unique

Really guys, what other title can a tanknetter have other than:

"Tanked for Sam and was paided a bonus"?

Moreover, the superplastic liner thus behaves much like a long rod penetrator.  

I noticed your HEAT projectile was missing the ass end with the fins.  They do tend to break off for the same reason the probe bends.  BTW, US HEAT rounds have been using a full frontal impact fuze for over 40 years.  It isn't just the probe that initiates the detonation, the shoulders of the round can also initiate detonation.  Lastly, I'm sure you merely overlooked this, the HEAT rounds don't utilize a long flash tube such as that for APFSDS.

Having dabbled in making youtube videos a bit myself, I can certainly vouch for this.  One can be right 98% of the time, but dammit, the times one is 2% wrong are just....painful.

The (much) heavier projectile is slower to accelerate. Therefore, a longer but slower burn time for the propellants is advantageous, so the propellant is merely lit at the back and burns forward. Also, you don't want to exceed the maximum chamber pressure by lighting it up all at once.

In this video ( https://youtu.be/bNjp_4jY8pY?t=2036) Nicholas seems to insinuate that the Sherman had almost as good frontal protection as a Tiger.

I've always read that because of overmatching (and most shells being thicker than the Sherman's 50mm) the Sherman didn't have anywhere close to the protection of a Tiger, despite that the effective thickness makes it seem that way, and that even the late Pz IV's 80mm hull front offered superior protection.

Is Sherman vulnerability exaggerated or is Nicholas forgetting overmatching?

7.5cm PaK40 penetrated later Sherman's front (64mm @ 47deg*) at 1100m. 85mm ZiS-S-53 from T-34-85 showed same performances. Going by table data (ok, big if) that is somewhat more, but not dramatically so than a distance those could penetrate 100mm vertical armor, about 900m. So his estimates is not really wrong.

*AFAIK, ballistic protection requirements were same for both early and late model Sherman glacis.

No, 85mm gun from T-34-85s gun could penetrate that at 1500+m, vs 1100m for Sherman's front.

In general, unless hit by really, really overmatching projectiles sloped armor in WW2 had better performances than simple trigonometry would indicate.
