MY Astro subscriber friends told me that the documentaries on the making of the Stormwater Management and Road Tunnel (Smart) system and the Petronas Twin Towers were superbly made and in every sense worth watching, and gave their thumbs up for these documentaries.

The former was aired on Astro some time this year while the latter was aired last year.

These documentaries could be educational, too, for those interested in the building and construction sectors.

I believe the majority of non-Astro subscribers would be grateful if other TV stations could air these documentaries.
