There's a double rainbow joke to be made here; I just know it.

What can you tell from a photo if you overthink it?

If you zoom out, you can see he just overflew LSD. Appropriate, no?

(Lake Shore Drive)

Hmmm. Looks like a 737 maybe. So, it's 100 ft long. Guess 200-250 MPH over the city. The separations add up to a third the length. So with 4 different exposures through color filters, that's roughly 20 milliseconds or so per exposure, or 12 full images per second.

Looks like about 4 of the lengths of tennis court on the ground is the same as the length of the jet. Call it 500 ft to 100 of the jet. Given vertical separation rules, the camera plane is at least 1000 ft above the jet (we hope). If we guess the jet is at 5000 feet, then the camera plane is at 6300 or so and the FAA is happy.

The jet is heading on almost a direct heading toward O'Hare airport with about 30 to 40 miles to go. I'm guessing it's heading there rather than Midway which is 6 miles or so due west of it at this point. But looking at the apparent length of the wings, it's banked to the left, so he could be turning toward Midway.

It's going so fast the camera couldn't even capture all three channels before it had moved. That's even better than the slow cellphone camera that made a moving train "tilt" like in a cartoon. Ever seen that one? It's in my LJ archive... somewhere; I might have to dig it up.

No, I haven't! Can you find it?

I have seen spinning propellors distorted by camera phones. That is some crazy fun stuff.
