You left out a decimal point. Do over.
Now look here, this is all getting far too silly.

Do we know what kind of camera was used for the picture ?
I'm really dredging the stagnant corners of the old brain, but am I correct in recalling that horizontal "window shade" focal plane shutters like the old Leicas could distort images if the subject was moving relaitive to the cameras shutter ?
If the camera was aimed at and moving "with"the B29s, the Nick going the opposite direction would seem to exacerbate the situation.
Interesting suggestion. I don't think it would happen that way, but the only examples I can think of show the item not being panned with, or that are passing, as being angled at the top and bottom, as they've moved left-to-right while the exposure was underway.
This is the classic example:
Note that while everything is 'leaning', all the dimensions (height and length) are still 'correct' - and the relative motion equates to two aircraft going in opposite directions (but much faster!).

Many of the film SLRs being still in use have shutter curtains which need 1/60 s for the full travel. With these, the slant in our example will be four times greater, about 4° or 8°, respectively — and this will be hard to miss. For a classic SLR, synchronizing only up to 1/30 s, the effect will be twice as pronounced, although you have to remember that it depends on the relationship between the curtain travel direction, camera orientation, and subject movement.
For your entertainment, here is a reproduction of a drawing from one of the old Polish photography books in my collection: Techniques of Modern Photography by T. Cyprian, published in 1949 (no, I'm not that old; just bought the book visiting Warsaw a few years ago). It shows the geometry distortion caused by focal plane shutters, as dependent on these factors. Interestingly, the example cameras chosen were Leica and Contax (two rangefinder legends), but also the Kodak Ektra. The Contax column is applicable to the modern digital SLRs — nihil novi sub sole!
My head still hurts!
