### Quitting job, and few more jokes

I have decided to quit my job as a personal trainer, because the weights are too heavy.
I just handed in my too weak notice.

My doctor told me I have high blood pressure and short term memory loss.
At least I don't have high blood pressure.

My wife yelled, "are you even listening to me?"
I thought that was a weird way to start an argument.

### Concorde

In 1969, the Concorde SST Supersonic jet aircraft, prototype 001, made its first flight from Toulouse airport in France. With tons of test instruments aboard, test pilot Captain Andre Turcat took off at 3:40 pm, followed by two chase aircraft for filming the historic flight, and for calibration purposes. The flight lasted only about a half hour, remaining at a subsonic speed with its landing gear and nose in the down position. The aircraft made a clean landing at 4:08 pm. It was not the first supersonic-capable airliner to fly, however, as the Russian Tupolev-144 first flew several months earlier, on 31 Dec 1968. The British prototype Concorde 002 made its first flight from Filton Airport, Bristol on 9 Apr 1969. It was not until its 45th test flight, on 1 Oct 1969, that prototype 001 flew at a supersonic speed, above Mach 1.«
