I thinks whats meant is that the average Russian Airliner belches out more gasses than western airliners.

And what evidence does he have that CO2 and CO3 from a Russian aircraft is more or less dangerous than CO2 and CO3 from western aircraft.

In February Airliners World it had an article about the IL-18 and it said if you stood behind it you would most certainly get poisioned…..which is kind of worrying

Genius… not to mention burned and and probably arrested as well. WTF do you think would happen if you stood behind Concord with its engines running? Is standing behind a Boeing considered a cure for cancer in the country you come from?

What type of large jet engine burning kerosene at a few thousand degrees is safe to stand behind. They must be very desperate the make them sound bad if they have to stoop to that.
