Qantas Empire Airways

In Australia in 1934 Imperial and Qantas (Queensland and Northern Territory Aerial Services Ltd) created Qantas Empire Airways Limited to extended services in Southeast Asia. But it was not until 1937 with the Short Empire flying boats that majestic could offer an 'all air' service from Southampton to the Empire. The journey to the Cape consisted of flights to Marseille, Rome, Brindisi, Athens, Alexandria, Khartoum, Port Bell, Kisumu and beyond by land-based craft to Nairobi, Mbeya and eventually Cape Town. Survey flights were also completed across the Atlantic and to New Zealand. By mid-1937 Imperial had completed its thousandth service to the Empire. Speed Wings Over the World, statue on a portal above the Empire Terminal's main entrance; by Eric Broadbent The Empire Air Mail Program began in July 1937, delivering anyplace for 1½ d./oz. By mid-1938 a hundred tons of mail had been delivered to India and a related amount to Africa. In the same year, construction was started on the Empire Terminal, intended by A. Lakeman and with a statue by Eric Broadbent, Speed Wings Over the World gracing the entrance above the main entrance. The terminal provided train associations to flying boats at Southampton and to the since closed Croydon Airport. The terminal operated as recently as 1980. Imperial Airways Speedbird logoCompared to extra operators it was lagging behind in Europe and it was suggested that all European operations be handed over to British Airways Ltd (founded in 1935) which had more contemporary aircraft and better organization. However in November 1939 both Imperial and British Airways Ltd were compound into a new state-owned national carrier: British Overseas Airways Corporation (BOAC). The new carrier adopted the Imperial Speedbird logo, which has evolved into the current British Airways Speedmarque, and the term continues to be used as BA's call sign.

Commercial Flight

The first commercial flight was in April 1924, when a on a daily basis London-Paris service was opened. Additional services to other European destinations were started all the way through the summer. The first fresh airliner was commissioned by Imperial Airways in November 1924. In the first year of process the company carried 11,395 passengers and 212,380 letters. The extension of service to the British Empire was not begun until 1927 when, with the adding of six new aircraft, a service was instituted from Cairo to Basra. But the first service from London for Karachi did not start until 1929 using recently purchased Short S.8 Calcutta flying boats, even then the passengers were transported by train from Paris to the Mediterranean where the Short flying boats were.

The buy of the 8 Handley Page 42 four-engined airliners boosted the range of services, in 1932 the service to Africa was extended to Cape Town.

Intelligence, IQ, and g

Intelligence, IQ, and g are very different. Intelligence is the term used in ordinary discourse to refer to cognitive ability.

However, it is usually regarded as too imprecise to be useful for a scientific treatment of the subject. The intelligence quotient (IQ) is an index calculated from the scores on analysis items judged by experts to encompass the abilities coverd by the term intelligence.

IQ measures a multidimensional magnitude: it is an amalgam of dissimilar kinds of abilities, the proportions of which may differ between IQ tests.

The dimensionality of IQ scores can be premeditated by factor analysis, which reveals a single dominant factor underlying the scores on all IQ tests.

This factor, which is a hypothetical construct, is called g. Variation in g corresponds very much to the intuitive notion of intelligence, and thus g is sometimes called general cognitive ability or general intelligence.
