And the usual arguments in the youtube comments section about which was the best fighter - Spitfire or Mustang. Eric Brown flew both so is as good a judge as any:
[The Mustang]was the best escort fighter in the world, make no mistake about that. But this was because it had incredible range, but the laminar flow wing fitted to the Mustang could be a little tricky. It could not by any means out turn a Spitfire. No way. It had a good rate of roll, better than the Spitfire. So I would say the pluses to the Spitfire and the pluses of the Mustang just about equate the pluses and the minuses.

If I was in a dogfight, I'd prefer to be in a Spitfire. The problem was I wouldn't like to be in a dogfight near Berlin, because I could never get home to Britain in a Spitfire...”
The Spitfire was an inter-war design that was capable of amazing development in a short period of time - from the 1030bhp early Merlin-engined Mk1 to the 2050bhp Griffon-engined Mk14 (there were other later marks that made the war such as the Mk21 but it wasn't a great plane initially and few were made). The Mk14 was still a handful according to contemporaneous accounts.

From this:

to this

in about 8 years.

My favourite use of the Griffon engine is the deHavilland Hornet. Built like a Mosquito, powered by a pair of 2030bhp Griffons giving a 470mph top speed and packing 4 20mm cannons under the nose. Sadly it arrived too late for WW2 but would have been a boost to the long range escorting of bombers, as well as in the Pacific conflict where the Sea Hornet's long range would have been very beneficial.

Quite right. :oops: No idea why I wrote Griffons. Got carried away, I guess.

Merlin 130 and 131.

"The electrical blueprints that orchestrate life"

"DNA isn't the only builder in the biological world -- there's also a mysterious bioelectric layer directing cells to work together to grow organs, systems and bodies, says biologist Michael Levin. Sharing unforgettable and groundbreaking footage of two-headed worms, he introduces us to xenobots -- the world's first living robots, created in his lab by cracking the electrical code of cells -- and discusses what this discovery may mean for the future of medicine, the environment and even life itself. (This conversation, hosted by TED's Chris Anderson, was recorded June 2020.)"

I recommend Ted and TedX talks for their education value.
"The TED Talks channel features the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design -- plus science, business, global issues, the arts and more. You're welcome to link to or embed these videos, forward them to others and share these ideas with people you know."

New hydrogen storage.

I see it took the Germans to show you Yanks how to do it :wink:
As a side note about the use of formic acid, thats what stings when an ant bites

Put this in here to mainly for the aero aspects of the wing, the engine matters they bring up may not be 100%. Did not want to taint the piston engined fighter topic, although it may be more appropriate there...


Is there any interesting videos on antique or WW2 era gun cleaning kits?(would be pretty interesting to see what was used during WWI and WWII era)
That's a really nice video, ngl!

Kimis cousins and the pressure wave
A prorata equivalent 300kt of TNT blast.
Trinitrotoluene, more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3
The tonne of TNT is a unit of energy defined by that convention to be 4.184 gigajoules
In terms of TNT equivalents what does a nitro engine produce?

Wow, the first (direct) wave and first reflexion can be perfectly seen in the black and white high speed shot, love it =D>

Seems relevant to this space.

Windtunnel work or even MAF engine sensors could benefit.
