This image the Yegoryevsk crash of the TU-144 CCCP-77111 appears to show a part of the wreck made of wood: picture of a part of the wreck
(picture source)

The inside looks like wood slats with rafters. Wood is sometimes used in airplane construction and has pretty good constructive properties, so I don't want to dismiss the idea a priori as crazy. Was it the case?

    $\begingroup$ sure, it is brownish, but that looks like standard metal construction to me $\endgroup$

  • $\begingroup$ Surely it was used in constructing the airplane - where do you think they got (some of) their jigs, stands, workbenches, manufacturing building, etc. etc. from? $\endgroup$

  • $\begingroup$ Wikipedia has a brief note on the crash in Yegoryevsk. That photo looked so much like France in the 70s I was fooled for a moment. $\endgroup$ Dec 23 '20 at 20:26

You're looking at a typical metal wing's innards with stringers (small lateral stiffeners made from aluminum angle) riveted to aluminum sheet, and the remnants of wing ribs also attached. The colour is zinc-chromate primer which ranges in colour from bright green (epoxy zinc chromate), to olive drab, to, that that case, yellow/brown.

There is no wood there. If any wood can be found in an airplane like the TU-144, it will be in the interior finishings or panels, or possibly internal bits or fittings that are usually made from plastic, say like a saddle that holds some kind of cylinder in place (in lieu of a plastic or rubber material). But as far as that picture is concerned, you are definetely looking at metal.
