Attempted Hijacking of China Airlines Aircraft

Further to my memorandum dated the 11th March, further enquiries have ascertained that a card found in the pocket of SHIH, the deceased Flight Support Engineer, indicates that he may have intended to hijack the aircraft with a view to landing in China.

2.

In addition to details of standard aircraft landing procedures,

a hand-written flight plan on the card also contained:

3.

(a)

(b)

흐

details of radar recognition procedure consisting of a triangular flight path to identify the air- craft;

co-ordinates and bearings for a flight to Paiyun (White Cloud) Airport, Canton; and

(c) alternative co-ordinates and bearings for a flight.

to Shantou (Swatow) Airport.

Figures shown on the card, a copy of which was given to China Airlines officials, appear to comprise a flight plan to Shantou, and are similar to those which were broadcast on the 23rd February by the Peoples Liberation Army Fukien Front in an 'appeal for Taiwan deserters'

4.

"

Details of the Peoples Liberation Army Fukien Front's broadcast message for Taiwan deserters and a copy of the flight plan are attached at Annexures 'A' and 'B'. From these it can be seen that the notes in the top right-hand corner of the card are almost a direct quote from the instructions for defectors from Taiwan to Shantou. "Distance 192 nautical miles on magnetic course of 285°, (on arrival) maintain heading 41° (towards the beacon) after a left turn of 180°", However, the --instruction stated that the beacon callsign was PQ on 369 Kcs, NOT 368

Kcs.

5.

The headings of 326° and 331° (listed at Point 4 on the left of the card) from Cheung Chau (one of the bearings on the card) would pass just East of Paiyun Airfield correct course 323°).

6.

It is assessed that the graph is a check list for approach and landing in more detail than expected of a qualified pilot and could be a written reminder for an unqualified or inexperienced pilot who intended to land an aircraft unaided.
