A United Airlines Boeing 787, Flight 108, experienced a suspected engine failure shortly after takeoff from Washington Dulles International Airport, prompting the pilot to declare a mayday. The flight, carrying 219 passengers and 11 crew members, was en route to Munich, Germany when the pilot reported the left engine failure. The plane then circled back and safely landed at Dulles approximately 30 minutes later, with all passengers deplaning normally. The flight was subsequently canceled and passengers were rebooked on alternative travel arrangements.

United Airlines flight makes emergency landing at Dulles after pilot declares mayday, and it’s a scenario that naturally sparks a flurry of questions and reactions, reflecting a mix of anxiety, reassurance, and even a bit of dark humor. The recent incident, which occurred last month, saw the pilot declaring “mayday,” the international distress call, and the aircraft making an unscheduled landing at Dulles International Airport. It’s a situation that, while not a daily occurrence, is more common than many might realize.
First and foremost, it’s important to clarify the context. While an engine failure triggers an emergency, it’s not always a race against the clock. Modern airliners, thankfully, are designed to handle such situations. They’re built to fly safely on one engine during all phases of flight, even during takeoff. Every performance calculation takes into account the possibility of losing an engine right at the takeoff decision speed (V1). The focus is on getting the plane back on the ground safely.
In the immediate aftermath of an engine failure, the pilots’ actions are methodical. There’s an immediate pause, an evaluation of the situation, and then a coordinated effort. The flight crew works through checklists, communicating with air traffic control (ATC), dispatch, maintenance, the flight attendants, and finally, the passengers. The primary goal is to control the situation. If there’s an engine fire or any suspected damage, the engine is shut down and the plane is landed as soon as practically possible. If the engine shutdown is for another reason and there’s no immediate damage, pilots will try to restart the engine.
Regarding the fuel situation, some airliners are equipped to dump fuel, while others are not. The 787, in this case, is able to. If there is no need, fuel dumping is generally avoided. If the engine is secured and the aircraft is performing normally, the aircraft might enter a holding pattern to burn off fuel until the plane reaches the maximum landing weight. While it sounds concerning to be circling for a couple of hours, the safety of the passengers and crew remains the highest priority.
It appears that there was some confusion regarding the duration of the event, with initial reports suggesting a two-hour holding pattern. However, it’s crucial to correct this. The plane was only in the air for about 30 minutes. The pilot probably requested a holding pattern after the situation stabilized to troubleshoot and consider restarting the engine. The time is likely to include both the taxi time and the time the plane spent in the air.
It is worth noting that dumping fuel can be a faster way to reach a safe landing weight than burning it, though not all jets can. When fuel dumping is an option, the decision is made jointly between the flight crew and the dispatcher. However, fuel dumping is not always permitted, particularly over urban areas. In those cases, the only way to reduce the weight is to burn fuel. The minimum altitude for dumping fuel needs to be high enough to allow the fuel to atomize and disperse before hitting the ground. The last thing anyone wants is a fuel spill over a populated area or into the ocean.
While a situation like this can be unsettling for passengers, it’s important to recognize the professionalism and expertise of the flight crew. Pilots train extensively to handle emergencies, and their actions are guided by established protocols and safety procedures. As an airline pilot notes, these emergencies aren’t necessarily time-critical, and the pilots have the time to evaluate their options. The ability to fly safely on a single engine in almost every stage of flight is a testament to the industry’s safety standards.
The key takeaway is that a “mayday” call doesn’t automatically equate to imminent danger. It’s a signal for help. The pilots are trained to address the situation and make decisions to prioritize everyone’s safety. The fact that this event wasn’t on the news until almost two weeks later indicates that the incident wasn’t as dramatic as the headlines might have suggested.
