an altitude in the grey zone between acclimatisation and deterioration, were unique; at that altitude the oxygen content of the air was half that at sea level. Initially, work capacity was half that at sea level, but it increased to two-thirds with acclimatisation. The party all lost weight, an indication of high-altitude deterioration. For lung and heart function assessment, oxygen and carbon dioxide is measured in lungs and blood. At sea level, blood leaving the lungs is nearly fully saturated with oxygen, but it dropped to seventy percent at the camp. An important finding was that during exercise saturation dropped further, sometimes below fifty percent, despite a huge increase in the breathing rate; this explains why climbing upwards at high altitude is extraordinarily exhausting even if feeling comfortable at rest.

There were to be three scientific camps where the bicycle ergonometer would be used: Base Camp (17,500 feet (5,300 m)), camp 3 on the neve (21,000 feet (6,400 m)) and Camp 5 (24,400 feet (7,400 m) on Makalu Col. At Camps 6 (25,800 feet (7,900 m)) and 7 (27,000 feet (8,200 m)) and the summit only alveolar air samples would be taken. Camp 3 was established by the end of April 1961 then Camp 4 (23,000 feet (7,000 m)). Camp 2 was at 19,000 feet (5,800 m)

Possible reasons for the official displeasure were international criticism of King Mahendra for shutting down Parliament, the wide publicity given to the ascent, or because Hillary attended the state banquet on 27 February, during Queen Elizabeth’s state visit, in a lounge suit rather than in a dinner suit with his decorations. Sir Edward (sic) Hillary and Mrs E. (sic) Hillary had been invited at the last minute.
