They said pure oxygen was all i for short flights in the and i i programs, but suggested for Apollo that NASA switch to a two-gas atmosphere--such as the 20 per cent oxygen-80 per cent nitrogen i wo a on earth.

Astronauts planning to take a space walk would have to "breathe a a a i of oxygen to purge their systems of nitrogen before stepping outside. Also, with nitrogen-oxygen, the cabin would have to be pressurized to pounds per square inch, compared with only 5.1 pounds for pure oxygen.

system. But it has disadvantages such a a i i sound squeaky, which could foul up communications, and of con- i heat a a from a man's body. Until now, the NASA decision to go the one-gas route for its early manned seemed a good one. Sixteen spacecraft a i a tolal of 20 men raced into space for periods up ilo 14 with no oxygen problems. Many precautions were taken.

Each spacecraft purposely was lo push out extra gases that could contaminate the oxygen. High heat resistant materials were used. The cnbins wore vacuumed. The crew and launch teams were schooled in the dangers of pure oxygen. In case of a fire in space, the a a could a i decompress Iheir cabin ridding it of Ihc fire-feeding oxygen.

They would a relied on i space suits for protection. Had last Friday's Apollo 1 accident occurred during the Mercury program, the astronauts could have snuffed out most of the a by pushing a button that would have blown off ilhe hatch and diluted the pure oxygen. On Gemini this could have been done by firing ejection seals if the gantry had been moved away from the rocket. Apollo has neither safety device. The only exit for the three astronauts was ithrough a double door requiring 60 to 90 seconds to remove.

That's too long for the approximately 15 seconds it took for the fire to gut the cabin. To 'build a quick ejection hatch for Apollo would have been a major engineering problem, a NASA spokesman said. He noted Ihe Apollo craft is a twin-shelled vehicle with inner and outer compartments requiring Hie opening of two hatches. A single section hatch might create a weak spot that could collapse under the heat and friction of re-entry, he said.

CAIN DETROIT (AP) General Motors, (the world's largest corporation, saw its 1966 profits all $333 million below the rec- ird it set in 1965. The dceline stemmed largely rojn a drop of almost $500 mil- ion in sales, but the firm still wound up with ils second-best year.

GM President James M. Roach said his firm's 1965 igures were swelled abnormal- because of a heavy carryover of car buyers who could not get new vehicles in late 1964 because of a GM strike. The preliminary 1968 report released Tuesday showed sales otallcd $20.2 billion, off nearly half-billion dollars from 1965. ClM'slQ66 showing was aided by a fourth-quarter which up in part for a sharp dip in the third quarter. The world's biggest automaker did not announce specific figures for the final quarter, but subtraction of previously announced nine-month figures from those for the full year showed almost no decline in sales and only a small drop in profit.

Indicated fourth-quarter profits were $553 million or SI.93 per share compared with $587 million or S2.05 in the final quqarter of 1965. Fourth-quarter sales came to $5.7 billion as against in the final three months of 1965. Worldwide sales of GM cars and trucks came to 6,617,000 last year, about eight per cent below GM's U.S. car sales last year were compared with 5,696,000 in 1965. GM had a record-breaking 745,000 people on its worldwide payrolls lasrt year and paid them $5.6 billion.

This compared with 734,600 workers and a $5.4 payroll in 1965. Stockholders came in for a healthy share too as total dividends paid them in 1966 amounted to $1.298 billion or $4.55 per share, compared to $5.25 per share in 1965.
