Thanks for the feedback folks - usually "doctored" photos don't quite cut the mustard but this pic seems quite genuine - if not, they have a package better than MS Photoshop!!! WDTBD - likewise I couldn't seem to find anything from the negative image which leaned towrds fake. And finally Skybiter - you don't mean that pic of a B707 in Lake Victoria about 300m short of the runway do you!!!
Thanks folks...
