20 surprising facts about UFOs that are out of this world

  20 surprising facts about UFOs that are out of this world Does intelligent life exist beyond our solar system? If so, are such beings capable of crossing interstellar space to pay us a visit? The question remains to be answered, but for centuries human beings have been seeing Unidentified Flying Objects. Some have even reported being kidnapped by creatures from afar (to engender animosity?). Here are a few surprising stories featuring encounters of the third kind.

Boeing 777s with the same engine as the one which caught fire after taking off from Denver will be temporarily banned from entering UK airspace.

Transport Secretary Grant Shapps announced the move on Twitter after two incidents involving Boeing 777s powered by Pratt & Whitney 4000-112 engines.

In one, a plane's engine caught fire and parts were reported to have dropped to the ground in the Netherlands.

Metal fatigue suspected in Boeing 777 engine scare

  Metal fatigue suspected in Boeing 777 engine scare Metal fatigue has emerged as the chief suspect in last week's spectacular engine failure on a United Airlines plane, which scattered debris over suburban Denver and led to dozens of Boeing 777 aircraft being grounded worldwide. In the wake of the Denver incident, Boeing said all 128 of the 777s with Pratt & Whitney engines were grounded following Saturday's emergency landing of United flight 328. Of the 128 planes, only 69 were in service while 59 were in storage.Besides United, which removed 24 planes from service, affected airlines included Japanese carriers Japan Airlines and All Nippon, and South Korea's Asiana and Korean Air.

That came after a United Airlines 777 bound for Hawaii was forced into an emergency landing on the same day as its right engine was seen engulfed in flames and debris plunged towards the ground.

All 231 passengers and 10 crew onboard, as well as those on the ground, were unhurt.

The US plane-maker has already urged airlines to ground all 777s with the engine, which exploded after take-off from Denver, Colorado.

Boeing advised not using them again until the Federal Aviation Authority (FAA) finds an appropriate protocol for inspections.

Currently, there are 69 such planes in service and 59 in storage.

Boeing said in a statement released on Monday: "Boeing is actively monitoring recent events related to United Airlines Flight 328.

United will still fly the Boeing 777-200 after a scary engine failure in Colorado — but the ones still flying have a different engine

  United will still fly the Boeing 777-200 after a scary engine failure in Colorado — but the ones still flying have a different engine United Airlines' fleet of 24 Boeing 777-200 aircraft has been grounded by the Federal Aviation Administration, but the aircraft will keep flying. A fleet of 22 United Boeing 777-200s are unaffected as they're powered by General Electric engines. Passengers booked on the 777 might still fly on the aircraft but others will be moved to different jets. Visit the Business section of Insider for more stories.

"While the NTSB [National Transportation Safety Board] investigation is ongoing, we recommended suspending operations of the 69 in-service and 59 in-storage 777s powered by Pratt & Whitney 4000-112 engines until the FAA identifies the appropriate inspection protocol.

"Boeing supports the decision yesterday by the Japan Civil Aviation Bureau, and the FAA's action today to suspend operations of 777 aircraft powered by Pratt & Whitney 4000-112 engines.

"We are working with these regulators as they take actions while these planes are on the ground and further inspections are conducted by Pratt & Whitney."

In the Dutch incident, witnesses heard one or two explosions shortly after take-off and the pilot was informed by air traffic control that an engine was on fire, Maastricht Airport spokesman Hella Hendriks said.

Reporter questions State Department spokesman whether Biden taking credit for Trump accomplishments

  Reporter questions State Department spokesman whether Biden taking credit for Trump accomplishments Reporter questions State Department spokesman whether Biden taking credit for Trump accomplishments An Associated Press reporter took State Department spokesman Ned Price to task Monday for suggesting that President Joe Biden was responsible for a policy that had started under the Trump administration. Price, highlighting a report sent to Congress, said some 18 entities have engaged in "good faith efforts" to scale back their involvement in Nord Stream 2, a controversial $11 billion pipeline project designed to transmit Russian natural gas to Germany.

"The photos indicate they were parts of engine blade, but that's being investigated," she said. "Several cars were damaged and bits hit several houses."

The development represents a fresh blow to Boeing as its 737 MAX returns to the skies nearly two years after the fleet was grounded following two deadly crashes.

In the case of the 777, the FAA had earlier ordered inspections of the hollow fan blades, unique to the engine model, be "stepped up".

Other recent incidents involving Pratt & Whitney engines include an engine explosion six minutes after take-off which forced a flight between Okinawa and Tokyo to turn back in November.

And another Pratt & Whitney 4000 series engine failed when a blade broke off on a United Airlines flight from San Francisco to Hawaii in 2018

In each of the incidents, no one was hurt.

Two of the engine's fan blades from the Hawaii flight were fractured and the rest of them "exhibited damage", according to a separate statement from the National Transportation Safety Board (NTSB).

United Airlines grounds planes after engine failure

  United Airlines grounds planes after engine failure The airline stops flying 24 planes after an engine burst into flames soon after take-off from Denver.The plane, carrying 231 passengers and 10 crew, was forced to return to Denver airport. No injuries were reported.

However, it added it was too early to draw conclusions about how the incident happened.

United Airlines, the only US airline to use the engine model in its fleet, is temporarily removing affected planes from service.

It said it will work closely with the FAA and the NTSB to "determine any additional steps that are needed to ensure these aircraft meet our rigorous safety standards and can return to service".

Japan has gone a step further and decided to stop operating a total of 32 planes with that engine, according to Nikkei Asia.

The country's ministry of land, infrastructure, transport and tourism also ordered the planes out of service.

Boeing's 737 MAX fleet was grounded in March 2019 following two fatal crashes in which 346 people were killed.

In November, the US aviation regulator cleared the way for its return to US skies, followed a week later by the European Union Aviation Safety Agency (EASA) and the UK's CAA.
