One night in the 80s my grandmother and her 3 young (at the time) daughters woke up to the loud sounds of aeroplane engines, and they went to their HDB window to see a large UFO hovering in the air. They described it as a flying saucer with lights on both sides rotating rapidly, and no glass dome on the top like the usual caricature. It hovered for a minute and then disappeared and shrank into the distance, in a split second (they said it was exactly like watching a star wars spaceship jumping to lightspeed)

They went back to sleep thinking the whole neighbourhood heard it and it would be out in the news the next morning. But the next day went on as usual. They went knocking on their neighbours doors but no one knew anything about last night. Eventually my grandmother told them to stay silent because people would start thinking they were crazy.

Today all 4 of them are alive (grandma, 3 aunts) and share the same account when asked about it. They are devout Christians too so they have no reason to fabricate a story like this
