Did we have the Brodie system already? Hanging on a wire for landing?

There's an L.1049 crew operating manual here: https://aviatechno.net/files/l1049c_...ing_manual.pdf Perhaps that contains some clues (I haven't checked yet...).
Edit: from page 117.
Pages 66 and 67:
From this, it would appear that the drag strut, which normally restricts forward and aft motion of the main gear leg, incorporates a hydraulic cylinder that permits some movement, damped by hydraulic fluid.

Whilst I was at Wenzhou in the late nineties watching the daily TU154 take off was a must. It had to backtrack the runway and there wasn't a turning circle so you could hear the twelve main wheels howling and screaming as it was turned around. It would then start the take off and as it passed you there would be an absolute pandemonium of noise and smoke. It would then disappear and one would then see it as it reappeared above the smoke haze retracting the undercarriage to get some altitude and leaving behind a trail of asphyxiated pigs.

I can't find a pic of it but I believe 1930s US airshow pilot Mike Murphy had a similarly configured aircraft named "Cheek to Cheek", though it could actually only be landed upside down if I recall correctly! The "right way up gear" was for show...

And it fits with the theme of this thread, as, note that there is an axle connecting the two wheels together, not specifically unusual, but it is carrying a torpedo. The Blackburd (and the Short Shirl topedoplanes) were built to the same specification and took off with their wheel/axle combo attached, but dropped them before the torpedo was dropped, landing on the carrier on those prominent skids inboard of the wheels...

I'm surprised no one's mentioned this yet...
Here's another one that is less unusual than the Komet, but made for tricky handling on the ground; look at the angle of those wheels.
For comparison, here's a Spitfire.

Nuuumannn; I'm led to believe that the splay on the undercarriage of the Me109 was for tactical reasons. The legs are actually attached to the fuselage. This means that once the wings are removed, the aircraft can be carried on the back of a lorry, or on a railway car. Not so easy with the Spitfire, which would have had to have some sort of supporting cradle. So I've been told by people who know about these things.

I suspect the splaying out of the gear was probably concerned with ground handling - making the wheel track wider than the very narrow track that would have resulted if the struts were vertical. A vary narrow track would have made taxiing - especially at high speed - much more challenging when turning.
There's a good account of flying a Bf.109E here: https://haa-uk.aero/document/flying-...hmitt-bf-109e/ (click on 'download' on the right). He discusses the reasoning behind the undercarriage layout on page 4/5.

Personally, and speaking as a Yorkshireman, I think that when a Yorkshire Drawing Office invests in ruler, they are damn well going to use it.
Not sure there's much "futility" in an aeroplane that was designed for manufacturability. IIRC according to "Narrow Margin" it took around a third of the man-hours to make a 109 compared to a Spitfire, and when first designed it was a world-class fighter (and arguably not too far short of that for much of the following 8 years). Features like a fuselage made from short flanged tube sections bolted together with no longerons made final assembly much quicker and simpler. It also allowed damaged mid-sections to simply be replaced rather than patched, arguably making it more battle-worthy. The design concept of having a fuselage with two separate wings rather than a fuselage and a 1-piece wing also made for much simpler manufacture. Remember that the very small numbers of spitfires available in 1939 was largely due to the difficulties experienced in ramping up production from the "Supermarine hand-built-by-craftsmen" to large factories. Spitfire depended on far too many large, hand-wheeled, compound-curved panels with tight tolerances in 3-dimensions (like the whole upper and lower wing LE skins).
Just putting the other side of the argument...

As a technician, I have no problem with simplicity of design and ease of manufacture/repair and, if the result is an aeroplane with an operational record and scope for development like the Bf109, then bring it on.
On reflection, perhaps "irony" would have been a better choice of word, when their focus on mass-production results in the manufacture of 3 aeroplanes, Apparently it flew like it looked. (It wouldn't surprise me if the wings could be stowed inside the fuselage for transportation).
