Arrr - that is very interesting. A11, if it referred to something other than "All" could have referred to the number of astronauts who were assassinated too? 
I thought the film was being used as a vehicle by Kubrick when I saw it a few weeks ago and saw that jumper the boy had on, that had the Apollo rocket on it.

Chapter: Did NASA Sabotage Its Own Space Capsule?
From NASA Mooned America! by Rene
Compared to civilian test pilots the astronauts were underpaid. However,
their perks were impressive. Their celebrity status instantly conferred upon
them all the bonuses usually associated with show business stardom. Each
night on the town provided them with all the young women they could
handle, plus free drinks in every bar in the country. They were also given
a government jet trainer as a personal toy.
Test pilots have a hazardous occupation which probably sees as many
fatalities per unit of time as do men in combat. However, before the first
Apollo manned flight ever cleared the launching pad eleven astronauts died in accidents. Grissom, Chaffee, and White were cremated in an
Apollo capsule test on the launching pad during a completely and suspiciously
unnecessary test. Seven died in six air crashes: Freemen, Basset
and See, Rogers, Williams, Adams and Lawrence. Givens was killed in a
When you reflect on their deaths in the light of the three-man-instant
crematorium one wonders. Add the fact that there were eight deaths in
1967 alone. One wonders if these "accidents" weren't NASA's way of
correcting mistakes and saying that some of these men really didn't have
the "Right Stuff."
After 1967, only Taylor died in another plane crash in 1970. An actuarial
statistician would probably go berserk over these numbers considering
how small the group was. Another weighty factor, even though they
were "hot" pilots, the astronauts flew their trainer jets only part time. And
add to that the fact that trainers are usually inherently safer than other
planes in the same class. It would raise his eyebrows to find how few of
these men would ever enter space.
I can't help but wonder what technicians serviced their ships—because
what we have here is an appalling "accident" rate. They were the finest
professional pilots in the world, operating government planes where costs
have little meaning. Yet they died. Even if we call the cremation an accident
we still have five more "accident" deaths in one year. Very interesting!
I also wonder what the death rate was among the other NASA
employees who were in position to know too much?
