The cause of death of the Challenger astronauts cannot be positively determined;
The forces to which the crew were exposed during orbiter breakup were probably not sufficient to cause death or serious injury; and
The crew possibly, but not certainly, lost consciousness in the seconds following orbiter breakup due to in-flight loss of crew module ...
I'm trying to trace this story through the steps, but the simplest answer is
What proof is there that these capsules contain powdered human flesh
obtained from dead babies?
None. Or at least, none has been provided.
The main source for the vast majority of these news stories in the western media appears to be an AFP Newswire story. This story ...
They might well have been (even "probably were") alive until impact with the ocean, but it's unknowable whether they were conscious.
Here is a NASA letter whose purpose is to summarize what's known about the deaths of the astronauts.
It's written by "Joseph P. Kerwin" (an astronaut/physician, M.D.). It says (I quote extracts from it below),
Yes, replication/duplication of fingerprints has been demonstrated through the following methods.
a. Gelatin/Silicone: Description of the process is present here and it further describes turning a two dimensional print into a three dimensional mold.
In 2000 van der Putte and Keuning systematically studied a number of fingerprint scanners and concluded ...
In theory, no, but the odds for it happening are really low.
This presentation has a slide with an overview of the literature on the subject. If I'm interpreting the chart copied below, estimations of the possible configurations of fingerprints (i.e. the probability of a given fingerprint occurring) range from 1.45x10-11 to 1.20x10-80. Given that the ...
This was actually tested in MythBusters (episode 74, which is in Season 8).
In fact, that personal perfume is strong enough that none of Jamie's bloodhound-busting tactics worked. He zigzagged and doubled back on his trail, ran through a river, washed and changed clothes, doused himself in coffee and cologne, and even covered his tracks in ground ...
A few years ago I have seen a presentation by Mark Benecke, a forensic biologist, here in Cologne (Germany). He was among the scientists who took the DNA samples from the skull. According to him, the fragments had been touched by everyone in the Russian institute, so the DNA could have been from one of the scientists in the lab.
The presentation is not ...
