OK sleepy time.
I was told by this old guy - talking mid 80's years old, we were at a fly-in at the time and I was listening to hanger flying stories from a bunch of old guys.
Him and a friend were flying a older Cessna 310/320 from Nor Cal to somewhere in Colorado, I don't remember the particulars. Appearently the early Cessna twins were a fuel managment work of art.

This was in the early 60s.
So anyway these two had worked a day and most the night on some work item for their business. They had a 4 am departure from Nor Cal, I believe to Colorado, said it was smooth air and they were in the mid teens, sun coming up, prop sinc working with a nice humm, Otto pilot doing his job, Things went quiet, engines quit from lack of fuel. That quiet is what woke them both up about 40 minutes past the destination.

Switch tanks, boost pumps on and the figure out where you at.
Not sure how much was BS or fact, but I enjoyed the story all the same.
C ya, Bub
