As for a Helo recovery limiting the mass that can be recovered, I thought that as well. But then I thought most midair parachute grabs that have been done in the past have used aircraft, so a C130 or C17 or C5 or even a big Ant would enable quite a heavy mass to be recovered at a reasonable distance. But I wonder what the FAA safety/cert case for this looks like.

I  also think recovery of parachute with a Helo will not be easy. The risk is that the  rotor down draft will collapse the canopy, even a ram air type, just as contact is being made;- just ask anyone whoís flown a parapente in moderatel turbulence.....they fold, twist up into a knot and drop like a stone..... then you cut away to deploy the reserve. I know this has been demonstrated with little canopies and a small Heloís for the Genesis mission (the attempted real recovery failed) so Iím not claiming itís impossible. I might have expected to have seen a practice work up under way.

Old post, I know, but just to point out that the biplane was not "anther project". The F.K.35 was designed from the outset to be a convertible airframe - able to assembled as either a monoplane or as an unstaggered, equal-span biplane.

A display model was also made of the monoplane configuration equipped with twin floats. Presumably, the biplane could also take a pontoon undercarriage.

Nice drawings, thank you.
The BV 144 was built in France by Breguet because they had nothing to do and B&V had no capacity anywhere. It was OK to do this because it was a civilian project, expected to go into production once the war was over. The Breguet engineers went to Hamburg for a while to get the hang of the design before going back home to build it.
Two prototypes were built, but nobody seems to know whether both flew. There is even a story that de Gaulle used one as his personal runabout for a while.
Some awesome stuff has been published in this thread over the last couple of years. Thanks folks!

But thanks for the lesson on staging and the upper limits of the sensible atmosphere.  It's wonderful you are around to tell us these things.

Somebody has to try educate the unwashed masses.
