I'm looking for a series of science fiction books I read in middle school. They would have been published before 1970. I am very fuzzy on the details, but here is what I do remember:
- I think the series may have had a British author. Many of the main characters used "Sir" as a title.
- In one book, featuring faster-than-light travel, a reference was made to "EMC clamps" which made the FTL travel possible.
- In the same book, as the ship approached the speed of light, the crew experienced blurred vision that had to do with this particular FTL mechanism. (Sounds hokey, I know. But it's one of the details I remember.)
Does this ring a bell with anyone?
