A-50's crew is 15 to 16 people, 10 to 11 out of them are high-skilled operators, mostly OF-3 to OF-5. Their education and training take decades. A-50 carries 20 tons of special equipment. The last A-50 was produced in 1990. If you see a date like 2011 - it is when it was modified pic.twitter.com/GkRPvuCYff
