David, get yourself down to the Mach Loop in Wales.
Google image search on Mach Loop...know a lot of togs who go there!
ps....only have a few secs for a shot sometimes!!!
Its all about skill, techique, exp, settings and lens used...and generally, knowing ones stuff.
The skill in shooting in flight shots be it  birds or aircraft...will not happen overnight, takes time,  patience, ones understanding of the camera/lens and its capabilities!
