“Earth Must be Warned!” – Astronaut’s Caution Surfaces Again

If she did scream ““Earth must be warned!”, what was Haigneré trying to warn us about? One theory is that she was convinced that Earth had been visited in the past by aliens who genetically engineered the human race. This could be linked to her work at the Pasteur Institute where some sources reported she was working on “Human/Alien DNA research.” There doesn’t seem to be any evidence of that, but there was a mysterious fire at the lab a few hours after Haigneré’s suicide attempt. No cause was determined and the damage was said to be minimal – could it have been a cover to remove sensitive documents on her research?
