What Happened to UA770?
UA770 flew from Barcelona to Chicago aboard a Boeing 787-9. During cruising altitude, the pilots declared a general emergency by setting their transponder to Squawk 7700—a universal code that lets air traffic control know something serious is happening .
They safely diverted to London Heathrow (LHR), landing on runway 27R. The diversion wasn’t a drama—it was a smart move .
What “Squawk 7700” Means
- It’s a digital SOS.
- It gives the crew top priority from air traffic control.
- It doesn’t always mean something exploded—it’s a precaution for anything serious .
Why Heathrow Was Chosen

What Came Next for UA770
The plane stayed grounded as mechanics inspected systems—especially the cabin pressure system—to make sure everything was safe to fly again .
