The Civil Aviation Department has ordered the Hong Kong Aviation Club to submit a report on an emergency landing by a light aircraft on the wall of Plover Cove Reservoir's main dam yesterday.
With two people aboard, the Cessna C152 aircraft landed on the 2km wall at 9.39am. The plane was reportedly undamaged and no one was injured.
Police said the emergency arose so quickly that they were only notified after the landing, so were unable to evacuate the few people visiting the dam at the time.
The reservoir is a popular site for cycling and picnics.
The plane was said to have approached the dam from the southeast and it was not known how far it travelled along the wall before coming to a stop.
Legislator Andrew Cheng Kar-foo said it was a blessing that no one on the dam was hurt.
