TWO low-flying jets seen by dozens of readers in the Gwent Valleys on Tuesday may have been US fighter planes.

Two American F-15 fighter jets were booked to fly low over Gwent on Tuesday evening, the Royal Air Force said yesterday.

Dozens of readers got in touch with the Argus with reports of an incredibly loud, low-flying aircraft flying at around 6.30pm over an area stretching from Abercarn to Gelligaer in the Rhymney Valley.

Some told the Argus that the plane flew as low as 300ft.

However a spokesman for the RAF couldn't say for certain whether it was the US F15s booked to fly in the area were the planes that had been seen.

He said: "If this was the case we regret any disturbance that was caused to people. We hope that understand this was essential military training."

Readers reported spotting an aircraft over Cwmfelinfach, Gelligaer, Llanbradach, Brynithel, Pontllafraith, Abercarn, Newbridge, Blackwood, Risca, Abertillery, Wylie near Blackwood and Wattsville.

Sasha Chivers wrote on our Facebook page: "It was very, very loud in Abercarn and my daughter froze and screamed."

Gavin Pope added: "Watched it from my garden, it came southwards from Tredegar way, down the valley, then did a 90 degree turn just past Blackwood area, then roared off much faster in a westwards direction. Very very loud!"
