This has been semi-well reported elsewhere (except, oddly, in the paper of record); James Horner. (Edited to add 2: NYT obit. In fairness, it appears that they were waiting for official confirmation from Horner’s people that he was actually flying the plane; other sources seemed to be basing their reports on “well, it was his plane, and he hasn’t called anybody since it went down to say ‘I’m alive!’, so…”)
Dick Van Patten: LAT. A/V Club. (Edited to add: NYT.)
(He was in “Soylent Green”? I need to watch that movie “again”, as I’ve only ever seen parts of it in the “edited for television” version.)
He was an attendant at the old folks suicide stadium.
