Watch it

“Secrets of the Dead: The Airmen and the Headhunters” (8 p.m., PBS). A documentary about a World War II American bomber crew who were shot down over Borneo and were taken in by a tribe of headhunters. Come on, how can that fail to be interesting?

“Glee” (9 p.m., Fox). The rookie musical series returns after taking a few weeks off for the World Series. Tonight’s focus is on the challenges and pain of wheelchair-bound Artie, and it promises to be an emotional episode that apparently had the cast in tears as they filmed it. So have your Kleenex within reach.

“Top Chef” (10 p.m., Bravo). The six remaining cheftestants try to create a breakfast-in-bed dish. Nigella Lawson guest-judges. Cross your fingers that this is the episode where Robin finally goes home.

Record it

“MythBusters” (9 p.m., Discovery). Why do cars always burst into flames whenever they crash in the movies? Tonight Adam and Jamie test whether that would really happen. Sniff sniff . . . . smell that? That’s a fireball approaching.

“Return to Duty” (9 p.m., MTV). I’m going out on a limb here, but MTV has an opportunity to pull off a pretty powerful show, in this special following former “Real World: Brooklyn” castmember Ryan Conklin, who’s currently serving his second tour in Iraq. Done right, it could be a poignant reminder of realities of the war that could hit home for a lot of young viewers.

Oddly Inappropriate, Yet Kinda Watchable

AMC is saluting America’s veterans by . . . . well, airing back-to-back movies about America’s favorite messed-up, violence-prone veteran, John Rambo. “First Blood” (8 p.m.) is actually pretty decent, at least by B-movie standards. “Rambo: First Blood Part II” (10 p.m.) is more of a blood-splattered cartoon. But I have to admit, it’s kinda brainless fun watching Rambo single-handedly win the Vietnam War, 15 years after the fact.

Skip it

CMA Awards (8 p.m., ABC). Never mind that I’m not a country music fan, I’m just bitter because it’s pre-empting “Modern Family.”
