First I had to resolve: 14D: STAG (Doe’s mate); 22A: EEGS (Some hosp. tests), I left the second “E” blank for the moment, uncertain if I should go with “EEG” or “EKG”; 2D: ELAL (Its inaugural flight was in 1948); and 3D: REPO (Pickup that gets picked up, perhaps), which made me think of one of my favorite movies from 1984, “Repo Man.”
All of which finally alerted me to my error at 13A, and led me to my correction thereof.
There were six clues connected with the inner puzzle today, which I found quite clever. In addition to Mr. Elon Musk, these included: 18A: DELEGATE (Scandal surrounding copy editors’ proofreading marks?); 28A: APPLEGATE (Scandal affecting iPhone owners?); 47A: FLOODGATE (Scandal in the aftermath of a tsunami?); 57A: TAILGATE (Scandal that implicates a detective?); and 61A: NAVIGATE (Scandal depicted in “Avatar”?), which I didn’t really get, but then, I never saw the movie.
