It was a warm afternoon in the mid-80s, when a hot air balloon landed in a quiet suburban street in Llanbradach.
No official records of the event exist, or details of what exactly happened on that day, in the middle of Glyn Eiddew, but it was certainly a memorable one.
Kevin Foad was around 10 at the time.
Wearing his favourite Ghostbusters jersey, Kevin thinks the incident happened in the summer of 1985, a few months after that film was released.
"I was in Glyn Collen, playing with my friends in the street," he said.
"I was having fun when we heard a very loud noise.

"Looking for the noise, I remember seeing a hot air balloon sailing, oddly close, over the roofs of the houses to the south.
"It took a few moments of looking to figure out what was going on."
He added: "The noise was the flame, full on, trying to maybe get the balloon back into the air.
"It was moving at a fair pace through the sky, as the wind had obviously given it about five to 10mph, so not fast, but it was a large object moving very quickly.
"We watched as it got lower and lower and eventually stopped burning as it seemed to be doing no good."

He said they saw it jolt as it disappeared behind houses at the end of their street.
"All the kids, and what adults there were in the street or looking out of their doors for the loud sound, all ran out into the street and towards where the balloon was.
"Usually, it was a quiet place, the only noise being the main road and the odd diesel coal train which echoed around the valley on a daily basis.
"The balloon obviously hadn't hit a house, as it was disappearing behind the roofs. Behind there would be the road, or the river and the river bank."
He said the estate was built on a flat, flood plain where the River Rhymney meandered through the valley, so the two sides of the estate were bounded by the river, and a very nice grassy bank.
"This seemed to land behind the last row of houses, backed by a road, the river bank of about the same width and the river sunk about four metres below the level of the road.
"We all ran around the estate, as seen in the pictures, kids and adults from all over the estate.
"Luckily, no cars were passing by, but I seem to remember one pulling around the corner and coming to a very surprised halt!"

Whoever was piloting the balloon did a fantastic job of landing it just on the road, he said.
"As I came around the corner, the balloon was deflating. Others have said another came down on the hill, but I don't remember this.
"But I remember seeing two or three others sailing by - all closer than you'd expect, one much closer but not so close that I thought it might come down too - and more on the horizon once I looked, more towards Caerphilly direction.
"I guess the wind was blowing them to the north/north east.
"I remember hanging around for a while. I was a kid, so didn't think to speak to those in the balloon - and we all respectfully kept away from the balloon as it flopped onto the riverbank."

He remembered a car turning up to get the lost balloon.
"A white trailer and I think a cream coloured car are the vehicles that turned up to collect the balloon. Luckily, they'd followed it!"
"We shared gasps and gobsmacked looks with each other, taking in the bizarre sight," he said.
"Then we went back to play football in the street, with plenty to talk about after supper."
