The University of Hong Kong has confirmed that the ongoing redevelopment of its Pok Fu Lam campus has been plagued with "extensive" defects. It says it is working to rectify the problems, adding that the safety of students and staff are its top priority. Wendy Wong reports:

It is still unclear what caused the crew of a Cathay Pacific flight to Los Angeles to abruptly abort the plane's take-off on Saturday while accelerating down the runway. An experienced aircraft engineer says although existing pre-flight checks are well established, additional checks, particularly on flight control systems could have taken place before the aircraft left the ground. But Warren Chim, the deputy chairman of the aircraft division of the Hong Kong Institution of Engineers, told Elvis Yu it was very rare for planes to abort take-off when they were heading down the runway:

A former Cathay Pacific pilot says a miscommunication may have led to the emergency slides being deployed. Peter Croagh, who was a senior check and training captain, said the Cathay jet was on the loading bay with wheel chocks attached by ground crew, so everything "seemed to be okay".

Government pandemic adviser David Hui says the new Omicron subvariants, especially XBB, have rendered the two most-used vaccines here ineffective in preventing the spread of Covid-19. But he says research he led at the Chinese University shows the jabs are still useful in provoking an immune response and reducing the risks of severe cases and death.

Customs officers have made a record seizure of contraband goods. The haul of electronics, wine, music records and endangered species, worth $1.5 billion, was found at the Kwai Tsing container port. Sean Kennedy reports:

A study commissioned by a think tank specialising in youth policy suggests that most secondary students choose to be bystanders when they witness school bullying because they believe that intervening may worsen the situation. MWYO conducted a focus group with 26 secondary students to learn about their responses and concerns when witnessing bullying. It also interviewed two teachers and three social workers to try to understand how schools address bullying. Angus Chan, a researcher for MWYO, told Janice Wong that most students felt they had a responsibility to intervene but did not know what to do:

Foreign business chambers and consuls on an inspection tour of Henan and Shaanxi provinces say they are eager to forge closer links with China.
