Is starting to piss me off.

I understand that people will make mistakes, but the number of them which I am seeing is making me question the folks they have doing their fact-checking.

Take, for example, the armament of the Huey helicopters in Viet-nam. They say the arrived in theater with 2 x 30mm machine guns. Not.

The only aircraft we have with a 30mm is the A-10 Warthog, and the recoil from a single 25 rd burst slows it, a lot.

That was bad enough, but they then said, it was quickly upgraded to a pair of 60mm machine guns. They then showed them, and mentioned them by name... the M-60, a .30 caliber machine gun.

Which replaced the M-1 Browning, a different .30 caliber machine gun. The biggest change? The M-60 uses a shorter cartridge.


In the grand scheme of things this is meaningless. Most people don't care enough about things ancient (or modern, for that matter) to know that the context they are being given about whatever bit of infotainment the History Channel is peddling, but on the flip side, if they are this clumsy in the little things, what sorts of mistakes are they making in the bigger things? I know they are victim to the problem of a small number of people giving them "expert" commentary. The American who teaches at Sandhurst has been used to explain everything from the close combat tactics of the Greeks, to the logistical/tactical problems which caused the US Army to not be interested in helicopters.

It seems that his being at Sandhurst is enough "gravitas" to make him an expert on anything which involves an army.

This problem isn't limited to the realm of television history though, we are prone to allow pundits to weigh in, as if they had expertise on things which they aren't expert on, and we do it, often enough, even after they've been shown to be clueless to the point of actually being dangerous.

And the thing to ponder, each of those barrels only fired less than 300 rds.

Mind you, those are heavy (even the non-DU are tungsten carbide penetrators).

The thing is, to get the velocity they need for those, they aren't using gunpowder, but rather a class 1 high explosive.

And the action is such that none of the recoil energy is diverted, it all goes into the frame of the platform.

Well, 300 rounds times 300 g powder equals ninety kilos of propellant burnt in each barrel. The metallurgist in me is whimpering.

Still, I'm thinking that stopping the bugger from melting is easier when its in a plane at numerous hundred knots.

Not really.

First, the Warthog (the only place in which that gun is used) only does a couple of hundred knots, and the weapon is in a more enclosd space than it was for that test-bed.

The real reason the wiring doesn't catch fire (as it does in that photo) is that a firing is 25 rds.

Even at that, the plane appears to stop... because it knoks a couple of dozen kts off it's speed.

And the casings fall down like heavy smoke.
