(Just checking the spelling there as I occasionally have problems with irritable vowel syndrome.) Moreover, the reference to my 'trusty old service revolver' should have read 'rusty unserviceable garden roller'.

Great image of this Boeing B-17 Flying fortress, Graham
Your shutter speed of 1/1600sec has rendered the propeller blades static
To get a prop blade blur switch from AV (aperture priority) to TV (shutter priority) & set the shutter speed to 1/250sec

Many thanks to 'brian17302' for the advice; very much appreciated!! All the best, G. 
I doff my virtual cap to you sir, and hand over to you my crown of drivel! A brilliant picture, you truly must have legs like Twizzle to get this perspective!Irritable vowel and service revolver!!!
Brilliant Sir, absolutely brilliant and I shall unashamedly use these in the future and claim them as my own!
Welcome to the funny farm, the food is pants, but it's always sunny here. Thanks, you've just made my day! Dave @ cell 3, the Asylum
Love the angle and the comp is good.
Brian is right about the shutter speed, but I would suggest working your way down to 1/250th (and beyond) over time as your panning improves. Dialling in a slower shutter speed is going to result in blurred images if your panning technique needs work.
Also no one wants to come away from an airshow with no sharp shots so take a few at 1/1000th, then once you have some keepers lower it down to 1/400th which will give you some blur and see if you can still keep the aircraft sharp. If you get that to work start lowering it even further.
For helicopters you need to go even lower than that so a mono pod can help.
I shoot around 1/100th if I can, but I delete many more than I keep so don't get disheartened.
