WATCH: Irish man describes horror Storm Isha flight to BBC news - 'it was very scary'

A Tullamore man has recalled a horror flight from Copenhagen, which attempted to land in Dublin twice and then Belfast before eventually landing in Liverpool almost 12 hours later, to the BBC News. 

Cormac Kelly works in Copenhagen in Denmark and was due to return home to Ireland on Monday, but Storm Isha had other ideas, causing mayhem for the passengers on board the Ryanair flight. 

He recounted that the flight from Copenhagen to Dublin was relatively smooth until they came close to Dublin when it "started to go downhill from there". 

As they made their first attempt to land in Dublin, the plane "came back up in the sky," Cormac said. 

The pilot said they were going to try again after a go-around, but the second attempt was unsuccessful and Cormac said, "it just wasn't going to work". 

"The plane was going from side to side, it was very rough," he said. 

The plane then landed in Manchester smoothly, with little incident. However, they were then held on the plane for 5 or 6 hours. "We weren't let off the plane, and nobody knew what was happening," he said. 

Some passengers disembarked in Manchester, but people who stayed on were told they had the option of returning to Dublin. 

"We were told that the weather had subsided in Dublin and it would be possible to land," he said. 

This was about 5.30pm. Cormac's phone had died mid-flight, so he couldn't contact anyone, and then they were told they were diverting to Belfast. His parents were expecting him to land in Dublin but were tracking his flight path online. 

"The captain said we couldn't even land in Dublin, the winds were way too strong, they were 60 to 70 miles an hour, he said. We tried to land in Belfast, and Belfast was a disaster - it was very scary. The tension in the air was so thick. Everybody was looking at each other. No one knew what was going to happen, as we tried to land," Cormac said. 

"We got to about 1,500 feet and the pilot had to go back into the sky, because he couldn't land. It was just so dangerous," he said. 

They were then heading for Newcastle, and then back down towards Liverpool. "What was meant to be a 45 minute to an hour flight ended up being three hours, back to Liverpool," Cormac said. 

The BBC presenter remarked that it was a "most incredible story" and added: "I'm surprised you can remember and work out where you are" during the ordeal.

Cormac managed to book a hotel with the help of his parents, Seanchail and Marie, in Liverpool and had to rebook his own flight. There was confusion over luggage and hotel accommodation for everyone after the arrival in Manchester which the BBC presenter noted "was a whole new story". He hoped the young Offaly man eventually managed to get home.
