As federal investigators look into yesterday's plane accident at LaGuardia Airport, new questions are being raised about when runways should be closed due to snow or ice.

Two cranes were brought in Thursday night to move Delta Flight 1086 into a secure hangar.

The aircraft skidded off the runway just after 11 a.m. while landing during the snowstorm.

The National Transportation Safety Board says it sent an investigator to secure the plane's flight data recorders.

The plane veered left, climbed a berm and crashed through a fence before stopping on a berm separating the runway from Flushing Bay.

It was carrying 127 passengers and five crew members.

No one was seriously hurt, but 28 people did suffer minor injuries. 

A photo exclusively obtained by NY1 shows extensive damage to the plane's nose which workers say contains flight radar receiver equipment.

The condition of the runway is expected to be one part of the investigation.

There is no rule about how much snow or ice leads to a runway closing.

The Port Authority says the runway where the incident took place was plowed just minutes before the plane landed. They also say other pilots reported "good braking action."

Passengers traveling in and out of LaGuardia Airport on Friday said the crash is unsettling, but that it shouldn't give anyone a reason to be afraid of flying.

"Doesn't faze me in the least, it was just one of those things that happened, and I'm very concerned for the safety of everyone and glad that so far everyone is okay," said one air traveler.

"It's scary when there's ice on the runway and you see it's all snow, but you have to take a chance. You just hope you reach your destination safely," said another air traveler.

The runway where the accident took place reopened Friday morning.

Air travelers are still urged to check with their carriers before heading to the airport.
