But that's an interesting point.<br /><br />Initially I thought that maybe it was due to the 777 flying particularly high or something (as the contrails etc. number is quite high), but it's no more, proportionately, than for their 'average' number. Given what you've said, it seems likely that they've made a mistake somewhere with what they consider average. Probably worth contacting them about, although I doubt I'll have the energy to do so!Heatherhttps://www.blogger.com/profile/17588832912375311757noreply@blogger.comtag:blogger.com,1999:blog-5683446064054569523.post-46658537051174306622015-08-08T00:07:13.590+12:002015-08-08T00:07:13.590+12:00What plane is Atmosfair comparing against?
