Low Tech Tips for Previous Wars

If you could go back in time, what would be the worst errors you could
correct for various wars. These should be things that could be
implemented pretty fast without first developing a whole new industry.

For example, planes in WWII had swept back wings when they should have
been swept forward.

Pretty sure the Germans (at least) tried forward sweep, but the examples
prototyped never made it to production.

There were quite a few planes with straight leading edge wings and all the
sweep at the back.

** Very, very few WW2 planes has any such thing - dickhead.

There is no advantage for a plane that does not approach the speed of sound
to have swept back wings.

The famous ME262 jet had wings that were somewhat swept, but that was an
after thought to correct a C of G issue.

See pic of the Bell X1 - the first plane to exceed the speed of sound in
level flight.

No sweep.

The aircraft wing was just an example and very possibly a wrong one at
that.

There must be all kinds of simple tricks in radar and other
electronics that appeared over the years that could be easily
implemented with the older technology.

Even today there are patents being granted that are not dependent on
modern technology and could have been invented a century ago. This
list would include that as well as anything else that appeared in the
mean time.

You are going back in time and they are demanding fast results.

** OK - think I have one for you.

The " G suit " or more correctly, " anti G suit " .

A low tech solution to the problem of fighter pilots blacking out in high G
manoeuvres.

Towards the end of WW2, practical G suits became available ( to the Allies
at least) and were VERY effective.

Had they been available earlier, as was technically possible, thousand of
pilots lives would have been saved AND the pilots that had them would have
possessed a HUGE advantage during " dog fights " and diving manoeuvres over
those who did not.

Very dumb not to have pushed forward the idea much earlier.

That's irrelevant since the request was for an example of one airplane
in WW2 with swept-back wings.

Your reply was that there was only one, when there were at least two.

A 'worst error' wouldn't be much of an error. If you're gonna screw up,
it should be much grander, like 'The BEST error' or 'Unsurpassable
error' or 'an error of ALWAYSWRONG magnitude'

As for wars, the vast majority of them could have been prevented years
before by the Natives killing every missionary landing on their shores
and then burning the ships down to the waterline.

** WRONG.

You cannot fairly include planes that were only ever experimental
prototypes.

Such planes did not go to war and whatever their characteristics, had NO
effect on the outcome.

OTOH, the 1000 kph Me163 did become fully operational and did shoot down a
number of USAAF bombers over Germany.

Which looks not too dissimilar to this plane:

Yes, but he said:

"For example, planes in WWII had swept back wings
when they should have been swept forward."

Seems to me like there's a lot of basic work
to be done before you can start a real discussion.

Depending on how you want to define "planes in WW2", there were, AIUI,
only one or two aircraft with wing leading and trailing edges swept
aft.

Ergo, Ian's statement that: "For example, planes in WWII had swept
back wings when they should have been swept forward." is, on its face,
seriously flawed except in one or two cases.

Moreover, I understand that a forward swept wing is inherently
unstable, with the technology needed to tame it unavailable in the
'40's.

End of discussion, I believe, unless you have something to add.

You should probably refrain from mixing crack, LSD & crystal meth all at
once - then you wouldn't fantasize I'd said things I didn't.
