a) 3rd November 2016: (Although I would soon realise that someone beat me to this by a month, I've been looking for a possible Tintin/Prometheus connection. Suddenly reading "Tintin and the Flight 714" the day before in a bookshop and noticed that there was a bit of a Von Daniken part to the plot, along with a large head statue too.
c) Sunday 30th April, 2017, I go back to "The Adventures of Tintin and the Flight 714" and look at the corridor featuring the statues, which I think is similar to the row of suits in Prometheus. This corridor leads up to the giant head in the story. (See also Just like "Fire in the sky" for another view about the corridor with the suits in Prometheus)

d) Wikipedia: "Hergé commented that with Flight 714, he wanted a "return to Adventure with a capital A... without really returning there."
He sought to provide answers to two questions: "Are there other inhabited planets? And are there 'insiders' who know it?"
Hergé had a longstanding interest in paranormal phenomena, and believed that a story with such elements would appeal to the growing interest in the subject.
He was particularly influenced by Robert Charroux's Le Livre des Secrets Trahis ("The Book of Betrayed Secrets"), which expounded the idea that extraterrestrials had influenced humanity during prehistory.
The character of Mik Kanrokitoff was based on Jacques Bergier." (https://en.wikipedia.org/wiki/Flight_714)
