The Wah Fu Estate "Mothership" Sightings

Wah Fu Estate sits on the southern edge of Hong Kong Island, in Pok Fu Lam, beside Waterfall Bay and Kellett Bay. Its towers look south over the sea towards Lamma Island. From the late 1970s into the 1980s, residents here reported something in the sky they never forgot. The accounts give different years: 1979, 1980 and 1985. No contemporaneous newspaper report has been found. The case lives in memory and retellings, in what HK01 calls Hong Kong's most representative collective urban legend.

One resident woke in the night. Walking to the toilet, they felt what seemed like an earthquake. They ran out to the corridor. Many neighbours were already there, looking up. Above Wah Tai House was a huge black object.

The witnesses described it in their own terms. A giant metal disc. Like a giant iron discus. A giant wok lid, or a straw hat. A big black shadow. Some said it was hexagonal or octagonal. It was as wide as a building, or as wide as two housing blocks, large enough to blot out the sky over the estate.

Its underside was alive with light. One account describes several lights of different colours, red, yellow, green, blue, constantly rotating and flashing, unlike the navigation lights of any aircraft. Others remembered constantly flashing white lights, or thousands of small lights. In one retelling a blue light shone, and the ground of the whole estate trembled.

It made no sound at all. It hovered above Wah Tai House for a few minutes, 5 to 7 in one account. Then it was gone, at high speed, out over the sea.

A resident known as Ah Kwan told RTHK that the object covered the sky over Wah Tai House at midnight. A former resident called Anita saw a large object pass slowly over the estate at sunset around 1985, its coloured lights glowing. Anita's friends did not believe the story. Weekend HK claims several hundred residents, from children to the elderly, came out to watch. Family stories still circulate online. Many people came out to watch, one recalls, frightened but excited.

According to the South China Morning Post, in 1987 the Hong Kong Observatory received reports of a ship as big as six soccer pitches hovering over the estate. No Observatory record of those reports has been found, and no definitive explanation was ever given. Weekend HK says police attended, found nothing, and the matter was dropped. Between 1984 and November 2010 the Observatory received more than 800 UFO reports. Some were satellites, stars or illuminated kites. Most stayed unexplained.

Four answers have been debated: a weather balloon, a secret military aircraft, an optical effect such as a mirage or a searchlight on clouds, or mass hysteria. Each meets an objection. The size and the lights. A crowded estate as a test range. A solid shape seen from many places. The consistency of the details.

Yet the details are not wholly consistent. Accounts differ on the year, the hour, the shape and the colour of the lights. They differ on where it went: the South China Sea, the sea near Lamma, the south-east, Lantau Island.

In 2010 RTHK's Hong Kong Connection revisited the story in an episode titled "Seeing UFO". TVB's drama Our Unwinding Ethos drew on the legend in 2019. Then came Ciao UFO, directed by Patrick Leung and shot mostly on location at Wah Fu. Its writers, Amy Chin and Kong Ho-yan, tracked down residents who said they had seen UFOs there. In 2026 it won Best Film at the 44th Hong Kong Film Awards. Today Waterfall Bay draws visitors to a supposed "UFO base".
