  1. Awesome WW2 experimental Aircraft

    Some more not-quite-made-it designs... https://oldmachinepress.com/aircraft-world-war-ii/
  2. WI: Irish Potato Famine Becomes British Potato Famine

    IIRC, the Irish & Scottish 'croft' potato was effectively a mono-culture. One single, high-yielding strain that was tolerant and productive. Until the Blight hit right in its Achilles' Heel... Paternal side of my family came from SE Ireland; IIRC, when their 'plot' rotted, they survived by...
  3. American space flight without Kennedy

    If they were not in such a hurry, perhaps Apollo 1 tragedy would not have happened...
  4. Awesome WW2 experimental Aircraft

    There's some awesome WW2 designs here, though many are post-war... http://www.xplanes3d.com/index.html
  5. No Franklin Dam Controversy? AusPol

    For OTL background... https://en.wikipedia.org/wiki/Franklin_Dam_controversy
  6. PC/WI: HAARP used as a pan-North American ABM system?

    BBC 1996 "Masters of the Ionosphere" == FWIW, as energetically unfeasible to shoot down MIRVs with HAARP as the original 1930s "Death Ray" to shoot down aircraft. Happens the latter give rise to RADAR... IMHO, wouldn't take much to 'harden' MIRV electronics against HAARP-grade EMP. Remember...
  7. What engineering projects could humanity do to have the biggest impacts on environment?

    "We could flood the Dead Sea from the Med." That's actually a viable proposal, provided you only do it part way... IIRC, the idea is to use the hydraulic head to assist reverse osmosis, supply lots of fresh & agricultural-grade water to area, run the waste brine down to the shrinking 'Dead...
  8. WI: Germany won the Battle of the Bulge

    IIRC, the US Army had been holding prox-fused shells in reserve for fear of the Germans copying them. When the Bulge turned nasty, they were deployed to ghastly effect on the German infantry and materiel...
  9. Earlier Development of Science

    "...would have been able to prove stellar parallaxes" IMHO, that's a long, long way down the line, as the shift is really, really small. OTL's first *validated* parallax was in ~1838 using a custom instrument. Also, until photography, it was very difficult to spot 'proper motion' within an...
  10. Alternate Routes to Berlin

    Like much of the far-fetched stuff in 'Popular Mechanix' or whatever, you must wonder if a lot of these think-pieces were commissioned to 'muddy the waters'... ( After Barnes Wallis' 'Bouncing Bomb', could the Germans ignore any notion, however absurd ?? ) IIRC, the MINCEMEAT deception in WW2...
  11. Earlier Development of Science

    You must wonder where the 'Alexandrian Tradition' would have led, if their library had not been burned by the Romans, then the Mullahs...
  12. How to forge "centuries-old" documents & artifacts today?

    Um, the art world has reported enough forgeries, with period canvases being re-worked. Sometimes, they were a genuine me-too 'In The Style Of' that was later 'talked up'. Sometimes, they have taken a leap in tech to resolve. Beyond multi-spectral imaging, there's x-ray emission spectroscopy...
  13. D-day paratroopers?

    IIRC, 'Band of Brothers' aside, enough paratroopers went in to make a real nuisance of themselves. That was the best that could be expected, and losses were scary. Still, it meant the Germans had to divert vital resources to 'rear security', adding to their difficulties...
  14. A More Plausible "Big One"

    "Stuart Slade wrote an (in)famous work of alternate history called The Big One, " FWIW, there's still sections appearing, novelettes filling in gaps of a much, much bigger, broader arc...
  15. Improving French 1940 tanks materially

    IIRC, the Lee/Grant began with rivetted armour. On test, the UK team discovered that shell-hits that did not penetrate would still pepper the crew with ricocheting rivets. So, welding was used...
  16. AHC: No horse-based steppe nomads

    "The domesticated llama and vicuna are already much bigger and stronger than the wild Guanaco and Vicuna" I didn't know that. Thank you.
  17. Improving French 1940 tanks materially

    Would something like the M3 Lee / Grant fit the available tech better ?? With the British mods... Per similar post above, lose the silly top cupola, keep a lower 'command' turret with a machine gun instead of the bulky 37mm. Not a 'proper' tank, but the 75mm sponson gun was able to gut early...
  18. AHC: No horse-based steppe nomads

    "once in Asia, once in North America and once in Patagonia." IIRC, the NA horse-cousins were hunted to extinction with the rest of the Pleistocene mega-fauna. Is there any evidence they crossed the Panama land bridge ? I thought the Patagonian etc Caballero horse-culture was a spin-off from the...
  19. Parameters for aerial torpedo training?

    As I understand it, sizeable waves caused two problems. First, harder to judge correct height for the drop. Second, catching a wave 'wrong' could either send the torp straight down or cause it to 'porpoise'...
  20. How advanced could Roman technology have gotten?

    IIRC, there was some spectacular use of water power, with tiers of water wheels for grinding corn... Of course, grinding such quantities requires that much to be available at one time and in one place, with a market. Which meant grain-ships... Slightly off-topic, but I vaguely remember a long...
