reading 'between the lines', there was a chance that the crew might just have survived
Afraid not BOAC. Their suits, boots, helmets etc were torn from their bodies and shredded. Portions of their boot soles were found to have been subjected to extreme temperatures also. Much of the medical evidence is redacted, but from my reading the suggestion is the bodies were highly fragmented and it was necessary to use DNA to "match" the pieces. A sad event as the loss of life always is, but by the sacrifice of such people who are not afraid to accept the risks is what brings about advances.
