This one, I still remember like it happened yesterday.
I was at my grandparents' apartment in Freeport, Long Island, spending a week with them during the first of what would become my annual summer visits to NYC. Just the day before, we'd gone to see Dock Ellis and the Mets get blown out by Greg Luzinski and the Phillies; watching the Mets get killed on a brutally hot day at Shea was a bummer, but that was all within what I'd already come to expect within the boundaries of experience as a baseball fan. The death of Thurman Munson, however, was not what I'd signed up for at all.
I remember being pretty freaked out the previous September when I'd heard that Lyman Bostock had been shot to death while stopped at an intersection in Gary, Indiana. But while I liked Lyman as a player, I felt no connection to him as a fan; I'd never seen him play in person, never saw him interviewed on TV, never rooted for his teams.
Thurman Munson, on the other hand, was the very embodiment of baseball to me. I saw him hit a home run in the first major league game I ever attended, a 4-0 defeat of the Tigers at Tiger Stadium. My Dad had scored us great seats behind home plate, about halfway up the stands, so I was able to observe Thurman at work. Even at the age of 10, I knew he was considered one of the top catchers in the game; and since that was right when I was going through the brief period of wanting to be a catcher (basically because the gear was cool, and you got to order the other players around on the field), I paid close attention to every move he made that day.

Squat, scruffy, surly and hard as nails, Munson had been named the Yankees' team captain in the spring of '76, their first since the great Lou Gehrig. He more than lived up to the honor that season, making the All-Star team for the fourth year in a row, hitting .302 with 17 homers and 105 RBI, and leading the Yankees to their first World Series appearance in a dozen seasons. That was the only season I ever actively rooted for the Yankees — I loved that pre-Reggie team with Mickey Rivers, Lou Piniella, Roy White, Chris Chambliss, Graig Nettles, Sparky Lyle (pictured above), Catfish Hunter, Ed Figueroa and, of course, Dock Ellis — and I remember watching crestfallen as the Reds kicked the shit outta them in the October Classic. Thurman hit .529 for the Series, second only to World Series MVP Johnny Bench's .533 mark — but the rest of the team hit .178, and he couldn't do it alone.
Despite his gruff exterior, Thurman was a sensitive dude, and he got extremely pissed when Reds manager Sparky Anderson — never, by his own admission, the most articulate man — told reporters after the World Series that "I don't want to embarrass any other catcher by comparing him to Johnny Bench." He won the AL MVP award that year, but it's doubtful that the honor lessened the sting of Sparky's words; Sparky later said that he'd tried to apologize to Thurman, but the Yankee Captain wasn't having it.
The next two seasons, of course, would be a non-stop riot of slights, misunderstandings and full-blown drama as Thurman inevitably got sucked into the three-way vortex of chaos involving George Steinbrenner, Reggie Jackson and Billy Martin. He came out of it all with two World Championship rings, of course (not to mention a lifetime .373 World Series batting average); but by 1979, he was so sick of the Bronx Zoo soap opera that he'd begun campaigning to be traded to Cleveland, so that he could see his wife and kids every day. An avid aviator, he'd begun flying home to Ohio after games in the Bronx and other relatively nearby cities, in order to get a little extra family time in. The man was old-school; he wanted to play baseball, but the bright lights of New York were nothing compared to the comforts of home and family.

At least, I know all that now, and understand why he was practicing takeoffs and landings in his new twin-engine Cessna Citation when he crashed it at Akron-Canton Airport on August 2, 1979. At the time, though, I didn't get it at all. I didn't get how this larger-than-life figure could be gone, just like that; I didn't get why he would even BE in a cockpit in the middle of baseball season, much less die horribly in one. I remember hearing the news on my grandparents' TV, and then locking myself in their tiny bathroom with the weird metallic wallpaper to shed some quiet, confused tears.
I also understand now — though I didn't then — why Thurman wasn't immediately inducted into the Hall of Fame, like Roberto Clemente had been. Though he was certainly one of the great catchers of his era, he sadly wasn't around long enough to put up HOF-worthy numbers, and his decline in production in '78 and '79 didn't exactly point to greater things to come. But hey, anybody who would actively torment a drunk Billy Martin on the team plane by cranking Neil Diamond on a boom box deserves an eternal place in the Big Hair & Plastic Grass Hall of Fame. Rest in Peace, Thurm.
