Are you saying that Nasa also "has pretty bad reputation in scientific circles."?
In the sense of the now falsified AGW they certainly are laughed at by many scientists.
More to the point, however, having taken the time to read D.P. Davies book (and interviewed some pilots on the subject at hand, among others) and also being very mathematically/scientifically well trained; Davies is not shown to be wrong either by the non-peer reviewed article or the of slightly higher quality article, by NASA.
