Theme: VELOCITY. Theme answers contain words that indicate rapidly and efficiently getting from one place to another
18 A. Academy attended by James T. Kirk: STAR FLEET. From the original Star Trek TV series: boldly going where no man has gone before. A Fleet is a group of ships under a single command. FLEET here is an adjective - as all the theme words are - indicating rapid motion. Fleet is also an enema, but we'll just let that go.
24 A. Artist with a record 32 American Music Awards: TAYLOR SWIFT. [b 1989] She's has some success. SWIFT is another synonym for FLEET. It's also a bird that, appropriately, holds the record for the fastest confirmed level flight, at 69.3 mph.
34 A. Deeply hurt: CUT TO THE QUICK. Literally, this means to cut through the skin to the living tissue; figuratively it means to be hurt and offended. Here, it's another synonym for SWIFT. It's also a brand name for flavored powders to make your cold glass or warm mug of milk a bit less bland.
49 A. Inviolable, as a rule: HARD AND FAST. This means it is fixed and definitive, not to be modified or avoided. The sense of fast in this expression, now otherwise obsolete, is "locked in place." It's the root of the verb fasten, meaning to firmly attach. In the puzzle, FAST is another synonym for QUICK.56 A. With immediacy, or a hint to the four other longest puzzle answers: POST HASTE. Yet another synonym for FAST. From my brief examination, it seems that this can either be a single word, or a two-word phrase, with or without a hyphen.
