Number 4 The Role of Parallax
If you’re observing the airplane from a moving vehicle, such as a car or train, the parallax effect comes into play. Objects closer to you seem to move faster, while distant ones, like airplanes, appear to move much slower or even remain stationary.
Quick Sea Story
It was a dark (mine shaft dark, my heart dark...) and un-stormy night during a WestPac.
We were flying at about 1500ft agl. At my 2 o'clock we picked up a white light but had nothing on our radar. We thought it was a small fishing boat.
It looked to be moving very slow, hard to tell, so we turned to investigate.
About a minute after our turn, the "fishing boat" flew over us at tremendous speed.
We picked up the navlights on the flying fishing boat about 30 seconds before the merge so I only crapped about half my pants.
