XXX listened to a lecture, our cosmonaut Alexei Leonov spoke there. I told them that one day they woke up and felt something was wrong. The oxygen content in the air is more than 50%. One spark - and the entire ship will take off in the air!

XXX when the glowing gas explodes in a closed space in a large volume - not to the infinity, not to the air, but to the noise.
