Scary moments in the sky over the weekend when an Allegiant flight bound for the Sanford Orlando International Airport from Grand Rapids, Michigan, had to make an emergency landing in South Carolina after a loss of cabin pressure.

The flight landed safely and passengers were put in a hotel for the evening. On Monday, those passengers boarded a new plane to take them to their final destination.

Two hours after takeoff, Allegiant Flight 683 experienced a loss in cabin pressure, causing the oxygen masks to deploy.

Passengers tell News 13 that the plane started a fast descent and they were told by the captain that they needed to get to a safe altitude to breathe.

Now a day after that emergency landing, folks are happy to be back with family and friends.

Inside the Orlando Sanford International Airport eyes were glued to the escalator and cell phones gripped in hand waiting for that first sight and hug from loved ones.

Passengers were still shaky after scary moments in the sky.

“Nobody really knew what was going on,” passenger Linda Williams said. “The oxygen masks dropped and we thought maybe it was an accident, but our ears started popping and then we realized that we were making the descent pretty fast.”

“It got cold in the plane and all of a sudden the oxygen masks fell down,” passenger Ida Tacker said.

“Flight attendant came and said put your oxygen mask on as fast as you can,” Williams said.

“I opened up my window for a split second and I saw just that we were going fast – going down pretty fast -- and as soon as I looked out the window they told me to close the window and not look outside,” passenger Alex Reszitnyk said.

But in all of this commotion, passengers say they were never told what went wrong.

“No explanation at all,” Reszitnyk said. “Just that the cabin lost pressure up in the air.”

Allegiant Air wrote a letter to the passengers that read, “We are very sorry for the disruption in your travel plans. Your safety is our primary concern and is not something we would ever compromise.”

Allegiant Air tells News 13 all passengers will be refunded for this flight and given a $200 voucher toward future Allegiant travel.

Still no word on what caused the loss of cabin pressure.
