Back muscles are the principal beneficia-ries of this exercise, yet the abdominal musclesare not slighted, and even the thighs comein for a moderate share of help. The com-posite benefit to the student is that thismovement enables him to carry himself moreeasily and with the weight of his body welldistributed. After halting the exercise on thefifth or sixth morning the man who is doingit well is rather conscious of the fact that heis standing both comfortably and well. At the beginning of the bend exhale thebreath. Inhale deeply on returning to erectposition. This may, at first thought, appearto be a reversal of the usual breathing methodin these movements. The reason for exhalingduring the bend and inhaling while return-ing is that the lungs are then filled for thenext bend, which is the harder half of themovement.

Red Jaguar XK140

The Jaguar XK120 was a sports car manufactured by Jaguar between 1948 and 1954. It was the first post-war sports car from the marque, succeeding the SS 100 which ended production in 1940 with the start of the war in Britain. The XK120 was launched at the 1948 London Motor Show as a test bed and show vehicle to highlight the new Jaguar XK engine. The car caused a sensation, which persuaded William Lyons to put it into production as a standard model.
The first cars manufactured in 1948 and 1949 had hand built aluminum bodies on an ash frame. Jaguar built 240 of these alloy bodied cars prior to moving to a more mass production XK120 in order to meet the demand for this popular model. With the 1950 model year a production version had a steel pressed body with alloy doors, bonnet, and trunk skin. Other features included torsion bar front suspension, and a removable windscreen.
Power came from a dual overhead cam 3.4 L straight-6 engine, Jaguar’s famous XK engine. With an alloy cylinder head and twin side draft SU carburators, the XK engine was very advanced for a mass produced unit, developing 160 bhp with the standard 8:1 compression ratio. This same basic design of the XK engine was used in 3.8L and 4.2L versions into the late 1980s.
The XK120 name referred to the vehicle’s impressive 120 mph (193 km/h) top speed – even faster with the windscreen removed – and at the time of its launch it was the world’s fastest standard production car. It was available as a coupe (FHC or Fixed Head Coupe, introduced in 1951), convertible (DHC or Drop Head Coupe, 1953), or the original roadster (OTS or Open Two Seater). An XK120 FHC can claim the only import win in NASCAR when it won NASCAR’s first road race at Linden Airport, New Jersey, June 13th, 1954 with Al Keller at the wheel. Earlier in the year, on 31 January / 1 February, an XK120 Coupe driven by Mrs D Anderson, Chas Swinburne and Bill Pitt had won the first 24 hour car race to be held in Australia, the 1954 Mt. Druitt 24 Hours Road Race.
The Roadster had a very light weight canvas top and removable side curtains screwed to the doors, which had no external handle – to open them you reached through the screen to pull a cord on the inside. It also had a removeable windscreen, which could be removed so that "aeroscreens" could be fitted. The DHC or Drop Head Coupe had a padded top and roll up windows. Both the FHC and DHC had an elegant wood veneer dash, whereas the roadster’s was leather. All models were manufactured with spats to cover the back wheel arch which enhanced the streamlined look, but when optional (from 1951) wire wheels were fitted, the spats had to be removed to make room for the hub spinners. There was also an M version (called SE for Special Equipment in England) which included increased power, stiffer suspension, dual exhaust, and wire wheels.
Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Nakajima J1N1-S Gekko (Moonlight) IRVING:
Originally designed as a three-seat, daylight escort fighter plane by the Nakajima Aeroplane Company, Ltd., and flown in 1941, the IRVING was modified as a night fighter in May of 1943 and shot down two American B-17 bombers to prove its capability. The Gekko (meaning moonlight) was redesigned to hold only two crewmen so that an upward firing gun could be mounted where the observer once sat. Nearly five hundred J1N1 aircraft, including prototypes, escort, reconnaissance, and night fighters were built during World War II. A sizeable number were also used as Kamikaze aircraft in the Pacific. The few that survived the war were scrapped by the Allies.
This J1N1 is the last remaining in the world. It was transported from Japan to the U.S. where it was flight tested by the U.S. Army Air Forces in 1946. The Gekko then flew to storage at Park Ridge, IL, and was transferred to the Smithsonian Institution. The restoration of this aircraft, completed in 1983, took more than four years and 17,000 man-hours to accomplish.

Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Boeing B-29 Superfortress "Enola Gay":
Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the first bomber to house its crew in pressurized compartments. Although designed to fight in the European theater, the B-29 found its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.
On August 6, 1945, this Martin-built B-29-45-MO dropped the first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Great Artiste, flew as an observation aircraft on both missions.
