He used a second curtain flash to get that result. It's a long exposure of maybe 10-30 seconds. The camera's shutter opens when the plane is still far away, letting it move towards the camera, leaving only the streaks of light visible. When the plane is above the camera and at the spot you can see it now, he fired off a very strong flash, just before the shutter closed. The flash illuminates the plane, letting it appear frozen at that spot, even if he used a long exposure. That's how you get that effect.

Quoting Monteycarlos (Reply 4): How would you do something like that though? Would it be using 'Bulb' mode (or equivalent)? How do you then trigger the flash at the end?
Some of the more advanced (D)SLR cameras will allow the user to choose between the more regularly used first curtain flash (where the flash fires as the shutter curtain moves up (i.e. opens), and second curtain, as explained by Jan. This allows dynamic creativity with photos at longer exposure for moving objects, so that they are pictured 'frozen' at the end of the blur - as here - or at the beginning of the blur - in first curtain usage.
I would assume that Martin chose a shutter speed, and selected second curtain in the functions of his camera, so the flash fired right at the end of the exposure just before the curtain drops (i.e. shutter closes).
I agree that it is a great photo - I shall wait to watch the viewing figures rise.
All the best.
P.S. I am guessing that it wasn't the built in flash that he used though .

Ah I see. Now it begs the question on just how powerful is this flash?

Thanks for nice comments. This thread is great surprise.
The setting was exactly as you mentioned. I used bulb mode, but found that even when the second curtain is selected, the flash fires twice- at the beginning of the exposure and also at the end. So I covered the flash by hand at the beginning not to disturb pilots, then kept the shutter-release button pressed and released it when the plane was above me. Camera fired second flash. Simple, isn't it?
It's better to use wide aperture and reasonable ISO, because amount of light reaching the plane decreases with square of the distance. Equipment used: Nikon D200, fisheye 10,5/f2,8, flash SB600 (not the Nikon's most powerful!!) and steady tripod. Setting f2,8; bulb (approx. 30s) and ISO 160. Not so difficult and worth trying.

I can't believe how well the flash lit the aircraft, how high do you estimate he was he when the flash went off at the end? Also how long till the cops showed up? Probably wouldn't happen to you there, but over here I'd be too nervous of getting busted to try. Absolutely fabulous shot though.
