A helicopter was flying around above Seattle yesterday when an electrical malfunction disabled all of the aircraft's electronic navigation and communication equipment. Due to the clouds and haze the pilot could not determine his position or course to steer to the airport. The pilot saw a tall building, flew toward it, circled, drew a handwritten sign and held it in the helicopter's window. T he sign said "WHERE AM I?"

in large letters.

People in the tall building quickly responded to the aircraft, drew a large sign and held it in a building window. Their sign said, "YOU ARE IN A HELICOPTER.'

The pilot smiled, waved, looked at his map and determined the course to steer to SEATAC (Seattle/Tacoma) airport and landed safely.

After they were on the ground, the co-pilot asked the pilot how the "YOU ARE IN A HELICOPTER" sign helped determine their position.

The pilot responded, "I knew that had to be the MICROSOFT building because they gave me a technically correct but completely useless reply.

In 1843, the first U.S. design of a typewriter that successfully typed was issued a patent to Charles Thurber of Norwich, Conn. (No. 3,228) as a “machine for printing by hand by pressing upon keys which contain the type, called ‘Thurber's Patent Printer.’” He was the first to place the paper on a roller and give it longitudinal motion with provision for accurate letter and word spacing. It had a wheel carrying the keys around its circumference. A roller provided inking. However, the machine was slow to use, and only a concept model. Two years later, he patented a design for a writing (not typing) machine, which he called a Chirographer (18 Nov 1845, No. 4,271). On 27 Jun 1857, British Letters Patent were sealed (No. 1805) on Thurber's invention of “An improved caligraph.”«[Image: Thurber's Patent Printer of 1843.]
