alternate history

Starting point Juan de la Cierva had already decided to continue his work motorizing the gyroplane's rotor. He misses his flight at Croydon which crashes in December 1936 because his car has a flat tire. He travels on the next flight, meets with Focke, and together they design and develop two...

Good sf doesn't just introduce new concepts, it explores the ramifications of those concepts. As HG Wells introduced tanks, DEWs, nukes, transnational organisations, and air power, he also explored what they would mean. Now, I really can't recommend : Lem enough. Under this topic, his 1964...

While I was reading about a report abou Sinking of Prince of Wales and Repulse, I suddenly wondered what history would have been like if HMS Indomitable had been assigned to the Force Z without any damage, or if the Implacable Class Aircraft Carrier had been built earlier than the original...

This was idea I had reading the merage IV threads, the idea being the the lockheed bribery scandal breaks in Germany befor the deal goes though leading to anything American becoming politically toxic, this leads to Germany (and though them the rest of the nato f-104 block) to buy the Mirage III...

I got this idea from some discussions I've had elsewhere and something that was brought up in a thread about making a "Spitfire into a baby Tempest". I sort of don't think that the Spitfire IX as built would be 100% suitable for what was mentioned in that thread for a "multi-role" fighter...

Lets send the MiG company on the path not chosen wrt. their 'budget' fighters. Instead, they make a spin-off of the MiG 19 that has a wing better suited for high speeds (not 8.74% t-t-c at root as on the -19, but under 4.5% as it was case with MiG-21; wing is also of the shorter span), and...

On a very topical note, a horror game that, appropriately enough, has recently returned from the dead. Not to be confused with the 2020 game of the same name. https://www.pcgamer.com/sorry-routine-is-back/ https://kotaku.com/routine-raw-fury-indie-horror-space-alien-isolation-pc-1849043193...

Model posted by Bob Gibson in What if and alternate history Facebook Group it's a speculative model reconstruction of fictional hydro version of Mosquito.

These are well worth a look. I wonder what FIXEDIT could do with a bigger budget! View: https://youtu.be/VVjdFBZCRQc View: https://youtu.be/zo8FhChnyq0 View: https://youtu.be/rTov2oSXR8M View: https://youtu.be/4irbMNQc8As

Many Tu-22M squadron fire cruise missile raid on enemy target and Japanese SHINKANSEN devastation screen shot from Japanese animation ″Future War 198X″. This post added Japanese SHINKANSEN devastation screen shots.

What if Messerschmitt 210 was produced based on V1 ? (Without any thousand modifications that made Me 210 a failure). I suppose that, probably an hypothetical Me-210A ( based on V1) could have been more success than real history of Me 210.

So what the title says. Say that cme the armistice in 1943 the Italians are able to tow away the ship to some secure port. Or alternatively if you want things simpler Italian commandos do not scuttle the ship in April 1945 and the Germans fail to sink her on their retreat. Either way you have...

The saga of HMS Hermes is well known. But it might have been different if the RN had followed the US example and kept her as an ASW carrier or interim Sea Control Ship. The US were introducing the S3 Viking on to their attack carriers but were keen to get as many to sea as possible. HMS Hermes...

I love airliners but hate the whole rigmarole of flying today..So here is another typical UK 75 thread. British Airways became one of the world's largest operators of the iconic Boeing 747 and even painted and.even painted one up in the colours of their predecessor BOAC. Imagine if instead of...

Not something I think fits in the alt-F11 thread but related to it, kind of. The RN is going to spend 16 million rebuilding Eagle, picking Tiger saves about 20-25 million over F-4 combine those two figures as your budget to build a new carrier with a 30 year hull life rather than spending 16 of...

This is an alternative history of Goddard's historical liquid rocket launch of 1926 and the succeeding development of a fictional experimental rocket airplane based on Goddard's designs. The advent of the design and its governmental support ultimately leads to a change in the course of the US...

I'm starting a new thread so that it doesn't hijack @airman's Do-19 evolution thread. Is the following feasible, plausible and reasonable? In this timeline the Do 19 and Ju 89 weren't cancelled on 29th April 1937. The Do 19 V3 and Ju 89 V3 prototypes were completed. 12 Do 19A-0 and as Ju 89A-0...

This was a discussion that began in the Gripen thread, but rather than have this "what-if" go off topic there, I felt it would be best to have a dedicated thread here as it's an interesting "what-if" As we know.. the Gripen replaced the larger/heavier Viggen. its a small, light weight design...

As we all know, the USAF went into Vietnam without a dedicated air superiority fighter and suffered for it, particularly in the early years with unreliable sparrows/sidewinders, no cannons on the Phantoms, and inadequate BFM training. Que the arrival of the F-4E, along with better missiles and...
