(CNN) -- New York's LaGuardia Airport reopened a runway closed after a jetliner skidded into the grass when its nose gear collapsed Monday, a spokesman for the Port Authority of New York and New Jersey said Tuesday.

The closure spurred two-hour flight delays early Tuesday as workers loaded the plane on a flatbed truck and officials inspected the runway, according to authority spokesman Chris Valens.

The Federal Aviation Administration said on its website that the average delay as of 6 a.m. had been two hours and 13 minutes. The disabled Southwest Airlines plane was being taken to an American Airlines hangar for further investigation, Valens said.

The National Transportation Safety Board said it's still considering whether to launch an investigation. The plane's cockpit voice recorder and flight data recorder were being taken to its labs in Washington.

On Monday, 10 people suffered minor injuries when the nose gear of Southwest Flight 345 collapsed upon landing at the airport, the Port Authority reported.

The plane was arriving from Nashville about 5:40 p.m. when the accident occurred. The nose of the blue-and-orange jet came to rest on the ground after the aircraft came to a stop, and passengers evacuated the aircraft on emergency slides.

"The aircraft skidded down the runway on its nose and then veered off and came to rest in a grass area between the runway and taxiway foxtrot," Thomas Bosco, the airport's general manager, told reporters. It stopped about halfway down the 7,000-foot runway.

Kathy Boles, a passenger aboard the Boeing 737, said a "strong jolt" shook the cabin when the gear failed and the nose slammed into the tarmac.

"It was just a bang and a bounce, and then a slam on the brakes and a skidding feeling," Boles told CNN's "Anderson Cooper 360."

"I feel extremely blessed to have come off that," she said. "It just really felt like the plane could have broken in half, it was such a hard impact."

Fellow passenger Anastasia Elliot said the situation was "pretty chaotic."
"We hit the ground pretty hard and slid," she said. "There was a lot of smoke filling the plane, just a lot of smoke and burnt rubber."

Another passenger said it felt like the plane crashed and then skidded to a stop.
