Thanks Chris Peterson,geckzilla and BMONE23,you are correct,I was just was slightly offended by Chrisfruits' word-coincidence.
I have spent years watching that flight go near a first quarter moon,And spent many hours preparing for that image.
Chris Peterson,I notice you have an observatory,so may be you do a bit of maths too.On the Ice in Space link,a chap named Dennis Simmons
has done some maths and made a graph and spread sheet of all the data,a few chaps have done the maths and worked out height of plane etc,etc.
According to the calculations,the 250th speed I used,as I captured the plane,the plane travel .69 metres, So yes I made a mistake in my previous post.
The spread sheets and data there is quite impressive,Dennis has even done a graphic diagram,well worth a look by everyone.One figure is quite amazing,
apparently-had my observatory been 40 metres either side of where it was,the plane would not be in centre,The chaps who have done the maths said they are open for correction.But so far it appears to be correct.They used some different methods of calculation-but the answers always seem about the same.
Yes,I do have another image I will submit to APOD one day,its a green comet at night,with airplane going right 'through' it,its wing lights 'frame' the comet.
Yes,most people left a very good comment,Sam's was amazing!
Thanks,Chris
