What to know about the deadly UPS plane crash in Louisville, Kentucky

Federal investigators looking into the deadly UPS cargo plane crash in Kentucky will closely examine the aircraft's maintenance records and data recorder after finding that one of its engines fell off during takeoff.

The plane crashed and burst into flames Tuesday in Louisville, killing at least 13 people and injuring nearly 20 others. The disaster temporarily shut down the largest UPS package distribution hub and disrupted flights in and out of the airport in Kentucky’s largest city.

No one expects to find survivors in the crash at UPS Worldport, the company’s global aviation hub. Gov. Andy Beshear said Wednesday that a handful of people remained unaccounted for, and crews were continuing to search for victims in an industrial area next to the airport where the plane slammed into businesses.

Here’s what is known about the crash:

Initial findings showed that the left wing caught fire while the plane was rolling toward takeoff, and its engine fell off, the NTSB’s Todd Inman said.

Afterward, the fallen engine was left on the ground beside the runway.

The plane has three engines, one mounted on each wing and another in the tail.

The plane should have been able to take off if one engine was inoperable or even if it had fallen off, said John Cox the CEO of Florida-based aviation consulting firm Safety Operating Systems. But that may not have been possible if one of the other engines was damaged or there was other significant damage to the plane, he said.

Cox and other experts said it resembles in some ways a 1979 crash that happened at Chicago’s O’Hare airport in that killed 273 people when the same General Electric engines detached from a plane. Investigators blamed improper maintenance before that crash.

The NTSB will look into the full maintenance history of the UPS plane as well as the engines and other components, Inman said.

But he said UPS has told the agency that the flight was not delayed and that no maintenance was performed right before it took off.

Flight records suggest the McDonnell Douglas MD-11, built in 1991, underwent maintenance while it was on the ground in San Antonio for more than a month until mid-October. It is not clear what work was done.

Aviation attorney Pablo Rojas said video suggests the plane struggled to gain altitude as the flames blazed along its left side.

The plane, bound for Honolulu and fully loaded with fuel, shredded the roof of one large building before erupting in flames.

“There’s very little to contain the flames, and really the plane itself is almost acting like a bomb because of the amount of fuel,” he said.

He said it’s hard to know if the pilot saw the flames, and that even if the crew realized there was a problem, aborting the takeoff might have been dangerous.

The plane crashed in an area dotted with scrap yards and UPS facilities.

It narrowly missed a restaurant bar and went down not far from a Ford auto assembly plant where hundreds of people were working, Beshear said.

The blaze stretched nearly a city block and destroyed much of the plane's fuselage, fire officials said.

DUBAI, United Arab Emirates (AP) — Iran targeted the world’s busiest international airport Wednesday and attacked commercial ships as U.S. and Israeli strikes rocked Tehran, while the United Nations' most powerful body demanded a halt to the Islamic Republic’s strikes on its Gulf neighbors that threaten global oil supplies.

The latest attacks marked an escalation in Iran's campaign aimed at generating enough global economic pain to pressure the United States and Israel to end the war that started 12 days ago. But there were no signs that the conflict was subsiding.

On Thursday, an Iranian attack sparked a major fire on Bahrain’s Muharraq Island, home to the island kingdom’s international airport. Authorities urged people to stay indoors and close windows to avoid smoke. The airport has jet fuel tanks, and other tanks in the area serve the kingdom’s oil industry.

Also, an attack on Iraq’s Basra port killed at least one person and forced a halt to operations at all the country’s oil terminals. Farhan al-Fartousi, the director-general of the General Company for Ports of Iraq, said the attack targeted a vessel in a ship-to-ship transfer area at the port on the Persian Gulf. Iraq’s commercial ports remained open, though the oil terminals had been shut, according to his statement carried by the state-run Iraqi News Agency.

The first week of war with Iran cost the United States $11.3 billion, according to the Pentagon, which provided the estimate to Congress in a briefing earlier this week, according to a person familiar with the situation who spoke on condition of anonymity to discuss the private meeting. The military reported spending $5 billion on munitions alone in the war's first weekend.

Both sides have dug in, hoping to outlast the other as the conflict upends trade routes, chokes supplies of fuel and fertilizer coming out of the Gulf and threatens air traffic through one of the world’s most-traveled regions.

Iran has targeted oil fields and refineries in Gulf Arab nations and effectively stopped cargo traffic through the narrow Strait of Hormuz, through which a fifth of all traded oil passes.

In response, the International Energy Agency agreed to release 400 million barrels of oil, the largest volume of emergency oil reserves in its history, in a bid to counter the war's effects on energy markets. The U.S. planned to release 172 million barrels of oil next week from its Strategic Petroleum Reserve to combat steep prices.

The U.N. Security Council voted Wednesday to approve a resolution demanding a halt to Iran’s “egregious attacks” on its Gulf neighbors.

Among the most recent attacks, four people were wounded after two Iranian drones hit near Dubai International Airport in the United Arab Emirates, though flights continued, the Dubai Media Office said. Firefighters extinguished a blaze early Thursday at a luxury apartment tower in Dubai Creek Harbor after an Iranian drone strike.

At Oman’s Port of Salalah, crews battled a blaze at fuel storage tanks there, according to the Oman News Agency.

“The international community is resolute in rejecting these Iranian attacks against sovereign countries that are threatening the stability of the peoples, especially in a region of strategic importance to global economy, energy, security and security of global trade,” said Bahrain’s U.N. ambassador, Jamal Alrowaiei.

The 13-0 vote in the U.N.’s most powerful body reflects Iran’s isolated position as it has aggressively responded to Israeli and U.S. strikes. China and Russia — two Iranian allies — abstained from the vote.

Their U.N. ambassadors called the proposal “extremely unbalanced” in not mentioning the strikes against Tehran that began the war.

Russia’s U.N. ambassador, Vassily Nebenzia, said it might leave the impression that Iran, “on its own volition and out of malice, conducted an unprovoked attack on Arab states.” Iranian U.N. Ambassador Amir Saeid Iravani said the resolution “deliberately ignores the root causes of the current crisis.”

Meanwhile, more attacks in Gulf countries were reported.

Drones were launched toward the cities of Irbil and Sulaymaniyah in Iraq’s Kurdistan region, while in the southern part of the country, an oil vessel flying the Australian flag was struck near Khor Al-Zubair Port, according to two Iraqi navy officials who also spoke on condition of anonymity because they were not authorized to comment publicly.

The official said 25 members of the crew were rescued. It was not immediately clear whether any others were missing.

On Thursday, sirens wailed and loud explosions were heard shortly after midnight in Jerusalem and other parts of Israel. The Israeli military said it was responding with another “wide-scale wave of strikes” in Tehran.

The fallout across the Middle East widened as Israel also struck what it said were targets connected to Iran-backed Hezbollah militants in Lebanon.

An Israeli strike hit a car Thursday in Ramlet al-Bayda, a major seaside tourist area on the eastern side of Beirut where dozens of displaced people have been sheltering. Seven people were killed and 21 others were wounded, the Lebanese Health Ministry said. The Israeli military press office told The Associated Press it was “not aware” of a strike at that location.

Blasts shook Beirut’s southern suburbs Wednesday, producing fires and plumes of smoke. Israel's military said the strikes were in response to Hezbollah firing dozens of rockets fired simultaneously across northern Israel. It marked some of the heaviest fighting between the two since the war began.

One rocket hit a house near the Israeli town of Karmiel, lightly injuring two people, according to Israeli rescue services.

At least 634 people have been killed in Lebanon since the latest fighting began, the Lebanese Health Ministry said Wednesday.

The U.N. refugee agency said at least 759,000 people have been internally displaced in Lebanon.

Iranian authorities say more than 1,300 people have been killed there, and Israel has reported 12 people dead. The U.S. has lost seven soldiers while another eight have suffered severe injuries.
