National Transportation Safety Board Vice Chairman Bruce Landsberg said the plane crashed at 9:11 a.m. Sunday at the Addison Municipal Airport. He says, "We don't know a lot about the people on board at this point."
Landsberg says the plane was headed to St. Petersburg, Florida.
He also said the plane had recently changed hands so it's not clear what the proper tail number currently was.
Jennifer Rodi, the NTSB's lead investigator on the accident, said it had previously been owned by a private charter company in Chicago.
Witnesses who saw a small plane crash say it struggled on takeoff and appeared to lose power.
David Snell, who was getting ready to fly from Addison with a friend Sunday morning, told KDFW TV that the plane didn't sound right on takeoff.
He says: "It looked like it was clearly reduced power. I didn't know if it was on purpose or not, but then, when the plane started to veer to the left, and you could tell it couldn't climb. My friend and I looked at each other and we're like, 'Oh my God. They're going to crash,'"
Peter Drake says he saw the plane crash into the hangar.
The plane "got onto the runway, went down the runway, started taking off. He got to about 200 feet, and I saw him starting to lose power and his altitude, and then I see him just roll over and came straight down right into the building,"
Ten people were killed when the plane crashed into a hangar at Addison Metropolitan Airport.
