Airliner flying over sea in the WV-2 image over Rio de Janeiro. Left panel: NIR2/NIR1/NIR1 R/G/B composite with the pan band superimposed. The NIR2-pan-NIR1 shift indicates a speed of ~80 m/s (290 km/h) over the ~0.35 s time lag. Right panel: NIR2/Red- Edge/Red-Edge R/G/B composite with the cyan head and red tail indicating the airliner movement over the 3 × 0.008 s (~0.025 s) time lag, presumably combined with a slight y-axis misalignment between the bands.
