Every few weeks an airline story goes viral — a diverted flight, a meltdown in row 9, a runway close call — and the same thing happens: everybody suddenly wants to watch plane documentaries. Not the 40-second news clip. The full black-box-audio, cockpit-recreation, "here's the exact bolt that failed" stuff. In the US, that itch has one name: Air Disasters, the Smithsonian Channel series the rest of the world knows as Mayday or Air Crash Investigation. It's been running for over two decades, there are hundreds of episodes, and it is exactly as bingeable as everyone says.
I'm a sports viewer first. I cut cable years ago because I was paying $90 a month for basically three channels, so I approach every "where do I watch this" question the same way I approach a game: what's the cheapest legitimate way in, and what am I actually giving up? For Air Disasters, that question comes down to a genuinely interesting head-to-head — Pluto TV vs. Paramount+ — with a couple of side options worth knowing about. One is free. One costs about as much as two coffees a month. They're built for completely different viewers, and I'll tell you which one I'd actually pick.
The main event: Pluto TV vs. Paramount+
Pluto TV is the free, ad-supported streamer that Paramount owns, and it has long carried a dedicated 24/7 Mayday/Air Disasters channel — just open the app (it's on basically every device made this decade), search "Mayday," and there it is, running episodes around the clock. No account required, no credit card, nothing to cancel later.
Here's how I'd describe it: Pluto is the sports-bar TV of plane documentaries. You don't pick the episode. You drop in mid-investigation, catch the reconstruction, stay for two more. For a lot of people — honestly, for most people who landed on this page out of curiosity — that's the whole experience they wanted, and the price is zero.
The tradeoffs are real, though. You can't choose episodes on the live channel, the ad breaks are frequent and unskippable, and the on-demand selection Pluto offers alongside it rotates without warning. If you're the type who wants to watch the TWA 800 episode specifically, tonight, Pluto will frustrate you.
Paramount+ is the on-demand answer. Because Smithsonian Channel lives under the Paramount umbrella, Paramount+ carries a deep bench of Air Disasters seasons you can actually browse and pick from, plus a pile of other Smithsonian aviation programming. The Essential plan runs about $8 a month with ads; the Premium tier is around $13 and drops the ads (mostly — live stuff still has them). One honest caveat: streaming libraries shift, and the complete multi-decade run isn't always all there at once. If you're hunting one specific episode, check the app's listings before you pay — Paramount+ offers a free trial, which makes that easy.
Small personal aside: Paramount+ is also where Champions League soccer lives in the US, so for me the subscription already does double duty. If a service can cover a midweek match and my "one more episode" documentary habit, that's a rare win for eight bucks.
The rest of the field
Philo (~$28/month) carries the actual live Smithsonian Channel, along with 70-some other cable channels and an unlimited DVR. Philo is famously cheap because it carries no sports at all — which makes it useless to me personally, and I say that with love. But if you want a broad, cheap cable replacement for a documentary-and-lifestyle household, it's the strongest play on this list, and the DVR means you can stack up Air Disasters episodes like a normal season of TV.
Tubi and the free shelf. Tubi, Fox's free streamer, usually has a rotating stack of aviation-disaster documentaries and one-off specials. It's not a reliable home for Mayday itself, but as a free second screen for this genre, it's worth a browse.
Netflix doesn't carry Air Disasters, but it owns some of the best one-off aviation docs of the last few years — Downfall: The Case Against Boeing and MH370: The Plane That Disappeared among them. Plans run from roughly $8 with ads to about $18 without. I wouldn't subscribe for these, but if you already have Netflix, they're excellent companion viewing.
The Nat Geo versions. Internationally this show is a National Geographic production, and Nat Geo-branded seasons have drifted on and off Hulu and Disney+ in the US over the years. Availability there genuinely changes; check the official apps before subscribing on that basis alone.
The comparison, at a glance
| Option | Typical price | What you get | Who it's really for |
|---|---|---|---|
| Pluto TV | Free | 24/7 Mayday channel, rotating on-demand, ads | Casual drop-in viewers |
| Paramount+ Essential | ~$8/mo | On-demand Air Disasters seasons, with ads | People who want to pick episodes |
| Paramount+ Premium | ~$13/mo | Same library, mostly ad-free | Bingers who hate ad breaks |
| Philo | ~$28/mo | Live Smithsonian Channel + DVR + 70+ channels | Cable replacers (no sports) |
| Netflix | ~$8–$18/mo | One-off aviation docs, not Mayday | People who already subscribe |
My actual recommendation
Start with Pluto TV. It costs nothing, it takes two minutes to set up, and it answers the question most people are really asking, which is "can I watch this show right now without pulling out a card?" Yes. You can.
If you catch the bug — and this show has a way of doing that — the move is a month of Paramount+ Essential. Eight dollars, binge what you want in the order you want, then cancel if you're done. That's the great unspoken feature of streaming that cable never offered: you're allowed to leave. I churn through services the same way for sports seasons, and nobody has ever sent me a strongly worded letter about it.
Philo only makes sense if you're solving a bigger problem than one show. And skip anything that isn't one of the services named above — if a site is promising the "full series free in HD" and it's not Pluto, it's not legitimate, and it's not worth whatever it puts on your device.
What might change (checked September 2026)
Everything time-sensitive in this guide lives here: prices are current as of September 2026 but creep up roughly once a year; Pluto reshuffles its channel lineup now and then, so the Mayday channel's name or number can shift; and the exact seasons on Paramount+, Hulu, or Disney+ rotate. The durable answer doesn't change, though — free-with-ads on Pluto, on-demand on Paramount+, live-channel on Philo. When in doubt, the official app's search bar beats any third-party listing.
That's my read. Watch one episode and you'll understand why this show outlives every news cycle that sends people looking for it. Now if you'll excuse me, there's a game on somewhere.
