Sometimes fighters pilots tried change flight path of V1 with a light touch of the wing.

Hawker Tempest/Fury, Meteor (I think) and maybe later Spitfires could do that - I think the one shown there must have been a 'test piece' otherwise it would have destroyed itself (and everything around it)! - but they did a lot of damage to London!

There was a V1 launch site 4 km from my birthplace, and a stray V2 made a hole in the ground 7 km from my birthplace. Luckily I wasn't yet around at the time; otherwise I would probably have gone and take a look at that hole, and died together with the 20-odd people who did, when twenty minutes after the impact the V2 timing device decided that it should have reached London by then, and went boom.

Frits thanks very much, when I found this previous photo the first thought was about you. But sometimes, only 1 percent of save can defeat 99 percent of the inevitable tragedy like with this unexploded V2 or Austria 1 race or how the arrested miner Dmitry, yesterday managed to escape from a Belarusian KGB/Nazi prison through a very narrow ventilation window and now he is save in Ukraine.
The V2s were first fired on London, but after the liberation of Belgium, the Germans targeted Antwerp. A few were fired on Paris and other French cities. This one fell on Rheims, but didnt explode

I'm wondering, how come that one is still so intact? - (even if it didn't explode).
Frankly I wouldn't have gone anywhere near the thing knowing just what they were capable of!!

I think that some were shot down just after they were launched - the only time they could possibly be shot down by an aircraft!

I think that there is a lesson here too for the two stroke engine - these things were versatile (like the two stroke) and they, c/w designer found their niche in space travel).

The two stroke engine would be excellent if used as a powerplant for just about anything (as well as drones etc etc)

...... but even more so when combined with a generator, it could provide simple, economical lightweight and useable power through electric motors for transmission (maybe even 'Ryger type' layout) ..... especially in places where power from an electrical grid is not available or unreliable (not all markets are in 'first world' countries!). - all better and much safer (environmentally speaking) than having power supplied by a crappy surplus nuclear power station bought on the cheap?

........ it could even be used in motorcycles!

I wonder too, as the V2 used to descend doing Mach 8; nothing anybody could do about it. So I have my doubts about the obvious soft landing in Reims.

Even as a powerplant for powerplants. Ever wondered how the engines of world's first jet fighter, the Messerschmitt ME262, were started? Each jet engine had a small twin-cylinder two-stroke boxer hidden behind its nose cone.

I am going to make something very similar but lighter and more fuel efficient with fuel injection

Keep up your enthusiasm - (have not yet read your link though) - hopefully we'll all eventually come to agree on a common purpose and be able to save the two stroke!
UPDATE - Yes, that would be a basic example of my idea (actually it looks like a good idea!) but that would only be one example (of many) of how to use a two stroke! ..... except that if I were going to produce something to show to prospective clients I wouldn't have gone out on to the street and grabbed the first person I could find and told him to come in and weld everything up for me! - never mind, chrome can hide a multitude of sins!!

That's it! we are not going to let the two stroke die out! - it is not only indispensable, it is man's and the planet's best friend! ....... but we still have to look after it and upgrade it to satisfy today's needs! ..... or it's gone!
So, to my way of thinking, the electric motor could be seen as either a friend or enemy (of the two stroke! ) - I prefer to see the two stroke controlling the electric motor, rather than the reverse!

JB, the 4.2 kg weight is impressive, but the fuel consumption of 800 gm/kWhr isn't, I would be aiming at 400. Obviously it is based on some existing hand held engine, all high pressure die cast parts I would guess.

Maybe we'll see you in the Foundry section doing some magnesium casting.

Obviously that guy has been listening to my ideas

- he got it wrong however ..... (I said "inexpensive and simple'"- but he thought that meant 'crap'!)
and it still uses the old style two stroke with all the inherent downsides and problems - never mind, - nice paint job!

I think his basic concept is fine though!

I wonder too about V2, but sometimes its happen.

(BTW An English guy told me this!) - ie that a typical English reaction to something big happening in the area is ....... "just ignore it and perhaps it'll go away!" - they've ignored this for quite a while!
