On Tuesday's Backchat, we learned more about China's domestically developed AG600 "Kunlong" amphibious aircraft, which has officially entered mass production after receiving production certification from the Civil Aviation Administration last week.

In the second segment, we stayed in aviation and spoke to an expert about the Air India crash which killed all but one person on board last week. We discussed the latest updates and learned more about the investigation process.

After the break, we talked about the community's growing support for breastfeeding. It's been a few months since Hong Kong's first breast milk bank came into operation. We found out from experts about how it's been providing much-needed support for premature and critically-ill babies.
