evidence that that particular pipe was part of a LM5 stage falling from space. I do not deny that LM5 parts could have fallen onto Ivory Coast in 2020-- that can explain your other arguments.

To me, the "burnt over most of its body" looks more like surface corrosion marks of many terrestial pipes-- Just compare the "burnt marks" on the pipe with those on the OTHER pictures you have shown above and, especially, the object resting on a tree branch below. The "burnt" marks on that pipe look very, very different from the others you have shown.

The other point is that the other objects you have shown are mostly spherical, or near spherical, and they are empty, which means that when going through the air, they have a very high drag to weight ratio. That makes them slow down very quickly (yet they still suffer very serious burnts as seen from your pictures) and therefore hit the ground at relatively relatively slow speed.

A long thin pipe, however, has the tendency to go through air along its longitudinal axis. THAT makes it have a very low drag  to weight ratio and therefore it can go through air at very very high speed (and can be expected to get more serious burnt marks as a result) AND to hit the gound end-on at very very high speed. At the moment it hits the gound, the momemtum of the the rest of the LONG THIN pipe, that is behind the leading section, should cause the pipe to bend, twist, deform....  much much more that what is seen in that picture.

Something doesn't add up with that particular pipe in the picture.
