Airport officials said no one was injured in the landing, but the airport was shut down for more than an hour.
A camera on top of Newswatch 16's studio captured the emergency landing. You can see the plane tip on its side as it lands.
"They tested the landing gear, flew in front of the tower, and the tower advised them it was not locking in place so the pilot made the decision to land on our runway, which he did successfully," Airport President Carl Beardsley said.
Airport officials said three people were on board the flight headed from Morristown, New Jersey to Philadelphia and they noticed the plane was having issues. The pilot decided to land just before 11 a.m. as soon as it was safe.
"It was a small single-engine plane and the people who operate the plane run a nonprofit organization where they take patients to medical facilities across the Northeast," Beardsley said.
No one was injured in the landing, but the airport was shut down for a little more than an hour while emergency crews cleared the scene.
"I'm used to almost anything that could happen. To me, it doesn't bother me, but I'm here for my sister and my great-niece and talking them through everything," Linda Hembree said while waiting for her great-niece to arrive.
One flight from Detroit was rerouted because of the emergency. The flight did not make it to Wilkes-Barre/Scranton until long after it was scheduled to land.
Linda Hembree and her family waited for an hour and a half for her great-niece to fly in.
"This is her first time flying, and to be put in a situation at a different airport and not be in here arriving at the same time, it's kind of throwing her for a loop," Hembree said.
However, once 18-year-old Emily Jones walked into the airport safely, it was all hugs and kisses from the family.
"How does it feel to be on solid ground?"
"Good," Jones replied, "but I still I have to get back into the car!"
The NTSB is still investigating the incident.
Everything was running business as usual at the airport by 1 p.m.
