Now, a change from just looking at old books. Today I look at this vintage C-130 Telex Landing & Take-off computer.

This is a nice set. First, there is the classic circular slide rule, called the “computer”. Very old school.

I am of the generation that finds it difficult using a normal ruler to draw a straight line, let alone being able to use a round slide rule to safely calculate the variables required for successfully landing a large and hulking plane like the C-130.

There is also the technical manual and it all comes in a nice case.

My dad was a flight engineer and his buddies were load masters for the C-130. What an airplane.
