It looks a bit like the early RN experiments, where they used RAM netting....

Well if we scale it up from 1/10th, it's probably use some kind of Junker corrugated skin too.

Lift may be the real enemy but it is accounted for in the design.  The issue here is more of building maintenance.  Whether the panels were blown off from lift from the outside or wind loads underneath once the building opens up you generally get more failures.  That seems to be an arch structure.  Those types of hangars were built in the 40's and 50's.  A lot of fatigue cycles, wet/dry conditions on those screws holding the panels in place over 60 to 70 years.  You would need to look at the segments of the fasteners remaining in the structural steel to determine if it was a pure lift failure or a combination of that with corrosion and fatigue.  I'm saying the later.  Grab yourself a copy of the Southern Building Code at the nearest library.  You will see that height of structure above terrain and other buildings is taken into account in developing the loads including lift generated by the wind.  Remember building codes are revised from time to time and the code that the hangar was built under is no where near as comprehensive as today's.  The body of knowledge is growing.

Interesting documentary of the Mil Mi-28UB, showing for example the airbag deployment and the rear compartment.

Some Oberth designs from "A che punto siamo con i razzi" by Alberto Fenoglio, which can be downloaded here : https://digilander.libero.it/fme/doc/Fenoglio1.pdf

Quite interesting, thank you!

Hi maxmwill,

I have both volumes of Ed's books, and they are well done and worth getting. If the price is too high look for it on used books sites or see if you can get from your local library (inter-library loan).

By the way, the author, Edwin M Dyer III is a member of this group. His user name is Hikoki1946, so you have already read his posts in this thread.  ;)

From what's visible so far, chances are it'll look exactly like the Dassault CG images released to date.

Note the diagram shows a prototype with an instrumented nose-boom.
