Good on u for the link.
I was invited to buy "internally" but I gave it as a gift to an
overseas friend.
There is another book which is more historically as it dated
back to the old Kallang airport ,XSP,PLA & how it moved to
CHangi in 1981. I bought it at T2 bookshop years back. It was in
B&W.
But the book you mentioned above gave a good insight into
the Modern Changi Airport .
Enthusiasts or students who are taking aviation courses or
airport engineering would do well to have one of these.
(LHS66 used to buy bulk for his students.HA! )
