Gregory Douglas, a journalist, conspiracy theorist, forger, and holocaust denier who claimed to have conducted telephone conversations with former CIA operative Robert Crowley in 1993, published a book titled Conversations with the Crow in 2013. According to Douglas, Crowley claimed that the CIA was responsible for assassinating Homi Bhabha and Prime Minister Shastri in 1966, thirteen days apart, to thwart India's nuclear programme. Douglas asserted that Crowley told him a bomb in the cargo section of the plane exploded mid-air, bringing down the commercial Boeing 707 airliner in Alps with few traces. Per Douglas, Crowley said: "We could have blown it up over Vienna but we decided the high mountains were much better for the bits and pieces to come down on". Conspiracy theorists point to the circumstances surrounding the death of Vikram Sarabhai, who showed no signs of illness prior to his death from a heart attack and was cremated without autopsy, as additional evidence of foreign involvement.
