What do you all think of Van Allen's comments?

What do you all think of Van Allen's comments?
Why shouldn't one of man's greatest achievements, landing men on the moon, be a great television show?
I suppose if you prefer fantasies like "man never landed on the moon" then you cannot stand factual documentaries like the moon landings! The landing drew the largest television audience for any live event up until that time so a huge amount of people agreed it was a great television show.
Dear Mr. Lambert,
In reply to your e-mail, I send you the following copy of a response that I wrote to another inquiry about 2 months ago --
Ø The radiation belts of the Earth do, indeed, pose important constraints on the safety of human space flight.
Ø The very energetic (tens to hundreds of MeV) protons in the inner radiation belt are the most dangerous and most difficult to shield against. Specifically, prolonged flights (i.e., ones of many months' duration) of humans or other animals in orbits about the Earth must be conducted at altitudes less than about 250 miles in order to avoid significant radiation exposure.
Ø A person in the cabin of a space shuttle in a circular equatorial orbit in the most intense region of the inner radiation belt, at an altitude of about 1000 miles, would be subjected to a fatal dosage of radiation in about one week.
Ø However, the outbound and inbound trajectories of the Apollo spacecraft cut through the outer portions of the inner belt and because of their high speed spent only about 15 minutes in traversing the region and less than 2 hours in traversing the much less penetrating radiation in the outer radiation belt. The resulting radiation exposure for the round trip was less than 1% of a fatal dosage - a very minor risk among the far greater other risks of such flights. I made such estimates in the early 1960s and so informed NASA engineers who were planning the Apollo flights. These estimates are still reliable.
Ø The recent Fox TV show, which I saw, is an ingenious and entertaining assemblage of nonsense. The claim that radiation exposure during the Apollo missions would have been fatal to the astronauts is only one example of such nonsense.

I believe that James Van Allen was talking about NASA's budget allocation at the time.
He was not saying that the moon landings were staged, (he referred to the "manned moon landings" as if they existed) but was saying that despite their entertainment value, they weren't actually advancing science that much.
His comments were those of a scientist closely allied with NASA but frustrated that he was unable to sway either public opinion or administrative will enough to fund some 'harder' science.

But his "greatest television show" comment seems to imply that television played a major role in the Apollo moon landing narratives.
I think that Van Allen was telling us that television is not a truth teller - it's all about the ratings "greatest television show".

The moon landing was televised live around the world and I expect that back in 69 it would have been he most viewed program at the time (my view).

Does a purported email from Dr Van Allen count as evidence of what his opinion was? I don't know, but here is this:
