Contrary to what this episode depicts, spectators could not see the explosion of the Mercury-Atlas 1 launch vehicle due to overcast weather.
At around 43 mins, when asked where Rene Carpenter is prior to a LIFE magazine photoshoot, one of the other Mercury wives replies, "Only her hairdresser knows for sure." This is a reference to a 1950s advertising slogan for Miss Clairol hair color.
