The source from 1968 differs from the more recent data because since 1968, engines and designs of planes have been advanced due to technological advances so that planes can fly faster. Of course there are other faster speeds. The US Space Shuttle flew at a record 16,000 mph (7153 m/s).
The short answer is that for a formal check it usually takes at least one to three days, but often up to a week. However keep in mind that many positions require an FBI background check which takes approximately thirty days and be aware that each situation varies because certain factors can hold this process up.
