ftb-

Those were the old days. Speed, mileage, gross weight.

You can't easily convert that contract to compare with today's numbers.

The "rates" were per minute. Not per hour. Every pilot's per minute rate was the same. Then we got paid extra on top of the per minute rate based on aircraft speed, mileage flown per leg and aircraft gross weight.
There was also night pay and a relatively larger international override, etc. etc.
