Did a quick 'histogram equalization' to bring out more detail, both in the positive and negative image. If this is IR, it certainly appears to show a good deal more heat concentrated on the underside of the left wing, compared to the right.
Many thanks for those; it also shows a larger 'plume' off the rear left wing.
Anyone got any thoughts on the speculation given by musicman in his post at #152? Looking at the series of slides and the depictions of the sensor dropouts, it seems to me that the 'orange' wire bundle was impacted and cut by plasma leakage. The rear sensors on the blue bundle stayed nominal, those tied into the orange bundle just dropped. That, to my mind, indicated that the leading edge RC/C was compromised.
