Also in the third segment is video of a USSR rocket launch followed by video of what apparently is a jettisoned tank or booster stage.
There are communities out there that make good use of jettisoned pieces of Soviet/Russian rockets that crash to earth in their vicinity. Good scrap metal is hard to come by out there, I presume. However, no telling what kind of toxic materials might remain on those rocket parts. I wouldn't be surprised if a failed "nuclear" powered satellite that crashed is now someone's chicken coop!
