Psychological warfare, Voice from the heavens

267 Squadron reformed at Kuala Lumpur on 15 February 1954 as a transport
and communications unit. It flew Pioneers, Pembrokes and Dakotas equipped
with loud-speakers known as 'Voice Dakotas'. For four years three aircraft
operated continuously on Voice Operations until the unit was re-numbered
209 Squadron on 1 November 1958. A 'Voice Operation' was a flight to a
particular area for the purpose of broadcasting messages directly to a
particular jungle target. Three aircraft had been specially modified for
this work - KJ810, KJ955 and KP277. Slung under the mainplane were four
loudspeakers delivering 500 watts of audio power, and in the main fuselage
a large diesel engine was anchored to the floor with huge bolts and metal
tie bars - this supplied the required 240v AC to the four amplifiers
situated in each corner of the main cabin.
