Yes, they were below the glidepath, and yes they blew the approach and had to go around: but this is hardly seconds from disaster or even a close thing. 600' at a normal approach speed is not "close" to the ground and 3.8 NM is more than 3 minutes at Vref which is certainly adequate time to respond.
These kinds of things happen and the only reason we're even hearing about this one is that it happened at SFO 28L.
I expected a little less sensationalism and a lot more intelligence from slashdot.
"Although a five-axle tractor-trailer loaded to the current 80,000 pound Federal weight limit weighs about the same as 20 automobiles, the impact of the tractor trailer is dramatically higer. Based on Association data, and confirmed by its officials, such a tractor-trailer has the same impact on an interstate highway as at least 9,600 automobiles"
So every time you go through a tollbooth, ask yourself "why isn't this truck paying 9600 times more toll than me?" The answer: you are subsidizing that truck.
Only through hard work and perseverance can one truly suffer.
