Interested in your thoughts and once again, thanks...
I hadn't heard about this...very interesting. Here's my reactions as I watched the video:
(1) In the early part of the video, they used a graphic showing a silhouette of a plane crossing the ocean. I found it amusing that it's a B-1 bomber silhouette.
(2) The sanctioned rest breaks in the cockpit must be a Canadian thing; the FAA doesn't authorize this practice. My feeling (and I think all pilots agree) is that taking a short rest, with the knowledge and concurrence of the other pilot, makes a lot more sense than fighting the need for sleep. We screw with our inner clocks a lot on this job and you can find yourself in this situation even if you showed up to work rested, especially on back side of the clock flying. The alternative is to ignore the need for rest and then fly the approach at less than 100% of your alertness and capability. [BTW, not really an issue for flights longer than eight hours, having three pilots, but several of our shorter flights to Europe operate with two-man crews. Canadian rules might be different on when augmented crews are required.]
(3) This guy is not the first to see Venus and think it might be another aircraft. But one giveaway is that no planes cruise with landing lights on. We might flash them when ATC calls opposite direction traffic, just so the other guy can pick us out, but normally they're off. [And flashing them is really unnecessary. When ATC calls traffic at altitude, it's really almost a courtesy. They don't let us get anywhere near each other and we're certainly not expected to "see and avoid" up there.]
When Venus is low on the horizon, there is an added optical illusion of other colors. You could swear you see twinkling red in that light and it's easy to wonder if that's another airplane's anti-collision light. Still, it's a little hard to give this pilot a pass. Taking that kind of evasive action based solely on the perception of a light is probably not going to be effective even if it was another plane. It is so hard to judge the relative position of another plane based on lights alone. I've often seen other planes up at altitude that clearly appear to be at our level and the TCAS shows we have 2000' of separation. The opposite occurs too, where a plane seems to be clearly above or below our altitude, but TCAS shows we are at the same flight level.
I had one similar "landing light" illusion once, which I think I related already itt. The Marines were doing night exercises at Quantico, Virginia and they had dropped some very bright para-flares, which slowly descend while casting the light they need for their operations. I was flying in a light airplane near Manassas that night and a group of three extremely bright flares looked to me like the landing lights on a very large plane. This was plausible since I was just south of Dulles airport. The flares weren't moving relative to me which indicates a potential collision course. I was getting pretty concerned and even descended to an altitude that I felt would be below any arrival path.
(4) The passenger being interviewed was thrown from her seat to the ceiling. Well, maybe she should have been wearing her seat belt as she has been told several times (and, according to the Canadian TSB report, the Captain had just turned the seat belt sign on a little before this incident). People should keep in mind that this isn't a buggy ride through Central Park, no matter how smooth it might be at times.
