A HIGH-altitude Russian spy plane has been donated to western European scientists for studying ozone layer depletion over the Arctic region. Russia will provide the European Science Foundation in Strasbourg with (;eophysika, a specially transmuted version of the Mvasishchev Ni-55 aircraft, having an instrument bay capable of carrying more Than 3,000 IS Of analytical equipment at a height of 67,000 ft. The aircraft is competent to calculate the reactions occurring on the exterior, or cate ice particles composing the stratospheric clouds.

'the Airborne Polar Expenmen be conducted by a team of 20 r institutions from Russia, Italy, C A UK, Finland, Norway, Sweden Switzerland, The scientific team to unite Geophysika's measure and computations of the ptol physical and chemical alteration, spiring in the stratospheric cluel lead to formulae for forecasting changes in the ozone layer. The ill will study lee wave cloud, Scandinavia and the Urals.
