Unfortunately, I know all too well what 'bobtailing' is.
I was questioning why they were at a gasoline pump meant for passenger vehicles.
And apparently that station sells diesel for cars, but not the "big rigs"?
These guys must have been like the 9/11 hijackers. They knew how to drive the truck and absolutely nothing else.

Yes, these guys were barely skilled at what they were doing.

There are no pumps for "big rigs" at that little Byers Sinclair filling station. The 9News website has a picture of the Byers Sinclair station, at http://www.9news.com/storyfull.asp?id=11281. This small-town gas station looks at least 30 years old, with perhaps one island of 1970's-era pumps -- only one pumps diesel, I'd guess.

And yes, this skill-gap pattern seems to fit the modus operandi of the 9/11 hijackers as well as Moussouwi, the "horizontal flier."
