🛩️ This is so cool: A Redditor living under SFO's takeoff path built a ceiling projection that maps every plane flying over their house in real time, using ADS-B, the open radio signal aircraft broadcast on 1090 MHz. Same feed as FlightRadar24, picked up with a cheap SDR dongle and beamed onto the ceiling.
THIS GUY LIVES UNDER SFO'S TAKEOFF PATH SO HE BUILT A CEILING PROJECTOR THAT TRACKS EVERY PLANE FLYING OVER HIS HOUSE IN REAL TIME
he uses a cheap $30 radio receiver to pick up the signals that planes broadcast while flying.
then projects them onto his ceiling in real time
when a jet flies over his house you hear it outside and at the exact same moment a plane glides across his ceiling labeled with the airline, aircraft type, and destination
pure black background so the projector's rectangle disappears and only the aircraft are visible
but he didn't stop at planes
it also draws the real sky behind them. sun, moon, bright stars, constellations, and live satellites including the ISS. all at their true positions for his exact location and time in real time
so he's lying in bed watching the actual night sky projected onto his ceiling with real planes crossing through it as they take off from SFO
there is a huge market for every man alive that runs outside to see the helicopter
vibe coded the whole thing himself with a cheap radio, a projector, and some clever software
grindr isn’t supposed to be used at home it’s meant for when the barista makes extra long eye contact and you wanna know if he’s gay or just looks like Josh O’Connor
Heathrow Airport is 80, and today marks the 30th anniversary of this unique air display commissioned to mark its 50th birthday.
In 1996 normal ops were suspended for 30 min for this incredible fly past of types associated with LHR over its history.
A truly unrepeatable event.
As a Delta pilot who's logged thousands of hours in the pointy end, let me tell you: these aren't "unruly passenger" footnotes.
These are flashing red warnings about the thin blue (and reinforced Kevlar) line protecting every soul on every flight.
Last night, Friday, May 29, 2026, United Airlines Flight 2005, a Boeing 737-900 (my former jet) flying from Chicago's O'Hare to Minneapolis with 147 passengers and six crew on board, turned into a real-life thriller at 35,000 feet.
A passenger tried to breach the cockpit. Which we are well-trained for. The crew squawked the hijack code (7500), diverted to Dane County Regional Airport in Madison, Wisconsin, and law enforcement swarmed in like the cavalry.
The hero crew and off-duty heroes on board subdued the guy. No injuries. Plane landed safe. Suspect in custody.
I remember the world before and after 9/11 like it was yesterday.
Post-9/11, everything changed. Cockpit doors became armored fortresses—designed to withstand bullets, battering rams, and desperate lunatics. Reinforced, locked, with secondary barriers that deploy when the main door opens for meals or bathroom breaks. Pilots don't just fly the jet; we become guardians of a sealed vault.
It’s a shame but it’s reality today.
Paris’ RER started with leveraging suburban rail networks from “the age of rail”
What made RER a huge success was the ability to break away from the long established ways of operating trains towards creating a regional rail network that served the growing region’s needs
In the 1990s, subway fare beaters were sentenced to well-publicized public service: "Thousands of riders--including insurance salesmen, artists, messengers, college students and even grandmothers--are being arrested and sentenced to painting Transit Authority buildings, scraping gum from stations floors or scrubbing toilets as punishment for fare beating."
See the NYT from February 18, 1991:
It always blows my mind that the German architect Walter Gropius who co-designed the (then) PanAm Building in New York was born in 1883.
He was 20 when the Wright brothers did their first flight, 25 when Model T was first produced... And somehow drew this.
