Abstract: It is shown that due to the dissociation of the molecular oxygen it ispossible to obtain inverted population in low pressure air by heating. As aresult of the quenching of the corresponding levels of the atomic oxygen thethermal superluminescent radiation is generated. It has been found that thethreshold of the overpopulation is exceeded at the air temperature 2300-3000 K.Using this effect a possible mechanism for the generation of the flashes of theradiation in air observed on the airframe of the space shuttle during itsdescent and reentry in the atmosphere is suggested.
