The open nullah stretches from Sha Ti Un straight out to sea.  The entire length is 3000 feet and is divided in three sections:

1st section: from Sha Ti Un to Po Kong Hill;  width 25 ft.  Work on this section is proceeding.

2nd section: from Po Kong Hill to Sung Wong Toi;  width 50 ft.

2nd section:  It connects up the former mullah which runs along Sam Tack Road to the sea.  Length 433 ft, width 20 ft.  Work is proceeding.

The work on the aerodrome is going on very rapidly.  Demolition of houses leaves little to be done.  With regard to reclamation, the strip from Po Kong Hill to Kowloon City Market is 6-7 feet above the ground level.

From a letter from Col Ride to Military Attaché of 12.5.43:

With regard to the secrecy of thefts of maps etc from the enemy, it was reported in WAICHOW that the Japanese did not know that the KAI TAK plan had gone til a report went back to HONG KONG via KWANG CHOW WAN.

We now know it was known many months ago in MACAO, because one was offered to our agent there and the offer was refused because the Consul told our agent one had already been procured!
