This aircraft is depicted as a Straits Air Freight Express B170 which carried freight between Wellington and Blenheim in New Zealand bridging the North and South Islands of the country. SAFE Air flew at its peak up to 17 Bristols, extending its services to the isolated Chattam Islands off NZ's East Coast. By installing a special sound proofed module the aircraft were able to carry passengers. The Bristols entered service in 1951 and the final 4 were retired in 1987.
Actual recordings of Bristol Hercules engines are included. Recorded from a TV documentary shown here about SAFE AIR
