Wow - the pic is great!!! erm - but, just curious about his explaination that you repeat regarding the taking of the picture......(not disagreeing with WHAT it is, just HOW it is....erm not clear...read on) As I understand the speed of sound is around 750mph....may be slightly out, but think it's ballpark.....anyways, if the plane was flying THAT fast and he clicked WHEN HE HEARD the sonic boom (given a) the fact that light travels faster than sound and b) his reaction time to the bang), then surely in the time it took for the sound to reach him the plane MUST have travelled more than the approx 15 foot that the 'boom cloud' has travelled down the plane? Does that make sense? And do I seem right or talking out of my buttock cheeks? He musta clicked BEFORE the boom. Musta....lol (",)
