Very good read.. While in the tower at Butterworth 40 odd years ago on a Sunday a Thai International was on a straight-in approach to Rwy 18 when a flight of four RMAF Tebuans [CL-41G] called for an immediate departure to the East to bomb a few CT's. They were on alert and this happened often. The Thai DC-8-33 was told to maintain 1500 and the Tebs cleared off Rwy 36 not above 500'. They cleared the runway with an early right turn as the DC-8 was approaching a three mile final. I cleared him to land and witnessed a magnificent slide-slip of that big beast and a perfect touchdown. The Captain was a Swede on secondment to Thai. Asked if he could do this everytime!!!
