The only aircraft that I know of in which you can see to the rear are military fighters, and even then, the view is limited, and the pilot has rare occasion to look back.

      Most Airbus planes have reversing cams, that let you see out the back of the plane from your seat.

      That said, the pilot couldn't have seen it from 5 nm (9.26km, for the non-plane nut /.ers), and to my knowledge, commercial airliners don't carry radar to pick up that sort of stuff. They carry weather and transponder radar, not the fancy military radar you'd need to detect flying pieces of metal in the sky.

    Most of the debris coming down is burned up before it even reaches commercial airplane altittudes. And it's not as if the sky is full of airplanes, the amount of sky taken up by airplanes is extremely small.

    Absolutely false. That was not space junk. It was atmospheric junk, which is not a problem because it falls, burns, and rapidly becomes either vaporized or on the ground. The problem with space junk is that it just sits there in orbit and never goes away. And the orbit that it is in could cross your orbit with an extremely high closing velocity.

    If we could get all of our space junk to become atmospheric junk, the problem would be solved.

      Just a couple of technical issues with your justification. First, it was space junk because it didn't start in the atmosphere (unless you count the moment it was launched, in which case I concede). Second, falling debris (whether atmospheric or otherwise)is a problem. Something with sufficient mass that survives the free fall will cause damage. Third, the orbit of space junk is the determining factor as to whether or not it goes away. A piece of debris in a low earth orbit or with a highly eccentric or

  • 5 nautical miles = 9.26 km
    A380-800 wing span (maximal dimension)=79.8m.

    The probability of debris atcually hitting the plane is (9.26/79.8)^3*10^9 = 1,562,515.33 times smaller than the probability of the event described in the article.
    • Even if you take 2D instead of 3D (which might be correct) it is still 13,465 times less chance.

Lets take the typical cruise speed of 544mph. 544mph ~ 9miles per minute and ~ .15miles per second. So if they were a minute slower they prolly woulda hit the trailing debris, and if they were a minute faster they prolly woulda hit the leading debris. That's crazyness!

    All major themes of these reports -- except the existence of a startling and bright fireball -- need to be treated with EXTREME SKEPTICISM. All available documentation shows the Progress de-orbit was performed exactly on time -- and if it wasn't, it would have burned up over an entirely different part of the globe. Twelve hours earlier, its passages across the Pacific were over Kamchatka and just south of the Aleutians -- nowhere near the airborne eyewitnesses. Range estimates by pilots of bright fireballs are NOTORIOUSLY inaccurate, and pilots have been known to throw their aircraft into violent evasive maneuvers based on seeing bright fireballs that were 100 to 150 kilometers away. This is GOOD for safety's sake -- always interpret a sudden visual stimulus in the most hazardous way -- but it's bad for 'dispassionate observations'.

    I witnessed the same thing about 20 years ago, as I was flying a B-52 westbound over Montana on a night-time training flight. A Russian booster re-entered the atmosphere in front of us, traveling north to south (it had just put a satellite into polar orbit), visibly burning and breaking up. Pilots all over the western US were reporting the sight, many thinking an airliner was burning and breaking up in their immediate vicinity.

    The funny thing was that even though the thing was at least 50 to 75 miles above any of us and hundreds of miles away from most of the pilots witnessing it, most were reporting it to be within a few thousand feet vertically, and less than 10 miles away.

    The human visual system is just not equipped to judge the size and position of something like this without a terrestrial frame of reference. All pilots are aware of that, but in the heat of the moment, the visual illusion can be extremely powerful.
