Even if Paul Hill were referring to orbiting manmade objects (as opposed to flying ones) I recall that NASA's Echo aluminized polyester balloon satellites (Echo I - Aug 1960, Echo II - Jan 1964) often reflected enough sunlight to be faintly seen during the day. The biggest problem was that in the early 1960's, without personal computers, modems and the internet, most people had no way to get pass predictions to know what they might happen to spot. The Echo balloon satellites were definitely visible during optimal satellite viewing conditions.
