What caused the deadly plane crash in Louisville? What we know and what we don't
Tuesday was a devastating day in Louisville after a UPS plane crashed during takeoff.
The catastrophic crash killed several people, injured many others and left more than a dozen unaccounted for.
It left behind an apocalyptic scene around the airport.
Here is everything we know so far and everything we do not.
The crash
The plane crashed around 5:15 p.m. as it left UPS Worldport, the company's massive global air hub located at Louisville Muhammad Ali International Airport. It was en route to Daniel K. Inouye International Airport in Honolulu.
It exploded in flames in an area where many businesses are located. It severely impacted at least two, shredding the top of a roof.
The crash sent a massive plume of smoke into the sky, prompting that stretched all the way north to southern Indiana. It was mostly lifted by Wednesday morning.
There was also a massive fire that spread nearly a mile. It took about six hours to get under control and firefighters could be battling hotspots for "a week or longer," fire officials said.
What happened?
The left wing caught fire during takeoff roll and the left engine detached, the National Transportation Safety Board said.
They are still investigating why, and said they won't speculate or determine what it is while they're in Louisville.
The NTSB has located the black box, which records flight data and cockpit audio to help investigators understand what happened during a crash.
It will likely be several days before they can get a read on it.

Victims
As of Wednesday morning, at least 11 people are dead and 15 are injured, and at least 16 people are still missing.
The governor said they do not expect to find anymore people alive, and say the number of deaths will likely increase.
One of the deaths is believed to be a young child, Beshear said.
Two of those injured are in critical condition in the ICU.
There were three crew members on board, and all of them died. At least four others who were not on the plane were also killed.
We do not have any names confirmed yet.
The plane
It was a 34-year-old McDonnell Douglas MD-11, built in 1991. It was Flight 2976.
It was fully loaded with fuel at the time, with about 38,000 gallons, which contributed to the blaze being so massive.
"Really, the plane itself is almost acting like a bomb because of the amount of fuel,” Aviation attorney Pablo Rojas told the Associated Press.
The fuel weighed about 280,000 pounds, officials said.
It reached a max speed of 214 mph and was on fire before it took off.
Retired UPS captain Norman Seawright, Jr. said its the third largest aircraft in the company's fleet, and one of the oldest.
"But it's still one of the most one of the most reliable ones that we have there," he said.
Airport impacts
Flights at the Louisville airport and Worldport were canceled Tuesday after the crash. As of Wednesday, the airport reopened, but some taxiways remain closed.
Some passengers told sister station WLKY they had to spend the night at Louisville airport.
WLKY observed some planes taking off from Worldport as well.
Worldport handles about 300 flights daily and sorts more than 400,000 packages an hour. It's unclear how this crash is impacting services.
Scope of damage
There are many businesses in the area affected by the crash.
The two businesses with serious impacts were Kentucky Petroleum Recycling, which the governor said was hit "pretty directly," and Grade A Auto Parts.
Fire officials said the size of the debris zone is large, about a mile stretch.
The chief said it will take "quite a while" to clear it up.
Investigation
The NTSB is leading the investigation and 28 members arrived in Louisville on Wednesday.
They are currently working without pay due to the government shutdown.
The Federal Aviation Administration is coordinating with the UPS team.
Environmental issues
was immediately issued as far north as Indiana, but was significantly down as of Wednesday.
The order is now in place just for a quarter-mile radius of 7501 Grade Lane, the city's hazardous waste drop-off just south of the airport.
The health department has advised any home or business within the shelter-in-place area to turn off any air intake systems (heat or air conditioning).
Beshear said Wednesday that people "immediately near" the crash site should avoid drinking tap water until further notice.
"Other areas are safe," the governor said. "If you are in the suburbs or in other parts of Louisville, you are as safe today as you've been any other day. The air is fine. Your water is fine."
State of emergency
Beshear also announced Wednesday that in the aftermath of the crash.
"This allows us to move resources more quickly through emergency management and through the Kentucky National Guard," the governor said. "It allows state resources to be used also through our agencies to be readily available, including disaster resource management, expenses related to response and more, as well as reimbursement."
In short, the governor said a state of emergency will ensure that groups that are limited in funding will be able to receive immediate or short-term help.
