The photographer for a national magazine was assigned to get photos of an enormous forest fire. Smoke at the scene was too thick to get any good shots, so he frantically called his home office to hire a plane. 
"It will be waiting for you at the airport!" he was assured by his editor. 
As soon as he got to the small, rural airport, sure enough, a plane was warming up near the runway. He jumped in with his equipment and yelled, "Let's go! Let's go!" The pilot swung the plane into the wind and soon they were in the air. 
"Fly over the north side of the fire," said the photographer, "and make three or four low level passes." 
"Why?" asked the pilot. 
"Because I'm going to take pictures! I'm a photographer, and photographers take pictures!" said the photographer with great exasperation and impatience. 
After a long pause the pilot said, "You mean you're not the instructor?"

U.S. Patent for Carriage Propulsion

In 1794, U.S. letters patent were granted by George Washington to John J. Staples, Jr., of New York, for what the inventor described as a "Carriage to be Propelled by the Mechanic Powers" (not steam power). However, reading the text of the patent shows that the specifications were vague, and the invention wholly impractical. It proposed five powers be used, including "The first power ... is the weight of the whole carriage ... which is raised up by the oval wheels in turning round, and when descending acts on the shortest lever. 2d Power is the weight of the top frame which supports the carriage body ... which being likewise wound up by the said oval wheels at the same or a different time acts in descending on the two next size levers."
