### Laying Turf

A painting contractor was speaking with a woman about a job. In the first room, she said she would like a pale blue. The contractor wrote this down and went to the window, opened it, and yelled out "GREEN SIDE UP!" In the second room, she told the painter she would like it painted in a soft yellow. He wrote this on his pad, walked to the window, opened it, and yelled "GREEN SIDE UP!" The lady was somewhat curious but she said nothing.

## Cross-Channel balloon flightIn 1785, Frenchman Jean Pierre Blanchard and American scientist and physician John Jeffries made the first air crossing of the English Channel from England to France in a hot-air balloon - the first international flight. This was the second of two balloon flights Jeffries financed. To accompany him, Jeffries chose Blanchard for his prior experience in balloon flight. The voyage across the Channel was successful, though not without difficulty, because to maintain height they were forced to jettison everything in the basket, including rope and most of their clothes. Their previous flight took place on 30 Nov 1784, in London, for the purpose of taking scientific and meteorological measurements.[Image: Blanchard (L) and Jeffries (R).] |
