The HOT air drove a turbine rotating at lots of RPM ( TTN can probably tell you how many ).
Actually
T -T that's one bit of useless information my shrinking brain hasn't retained, although it refuses to relinquish such nuggets as the magnetron and klystron frequencies of the H2S radar!
I only experienced a "hard hose" on the centreline once, when doing a tanker - tanker slot out of Luqa. All was well when it trailed, but the receiver called a hard hose, and a quick glance showed the motor frequency fluctuating wildly. Fortunately we were able to wind the hose in and get the HDU raised, but this meant that we were now the receiver, and had to take over the long slot and get back to Malta several hours after the other guys
