Harrison's First Chronometer
This photograph shows Harrison's first chronometer, developed between 1729 and 1735 in response to the British Government offer of a 20, 000 prize to anyone who could solve the problem of an accurate marine timepiece to aid navigation. Harrison did not win the prize with this chronometer, but he claimed the prize in 1761 with his fourth chronometer. To win the prize the timepiece had 'to be within 30 miles of the truth', in terms of longitude-time, on an actual voyage to the West Indies. This photograph is used in an advertisement for Tampimex Oil, a London-based oil broker. Photograph by Heinz Zinra"

Power and control in R101
The first diesel-engined airship: power and control in R101. Illustrations of some of the features of R101: a power car, the chart room, and mooring arrangements. The Illustrated London News states that "every precaution has been taken to guard against the possibilities of fire, and for the first time petrol engines have been superseded by engines burning heavy fuel oil" [diesel] which is less flammable. However this did not stop the R101 from crashing near Beauvais, France, on its maiden voyage and bursting into flames, killing 48.
