I've driven past the accident site several times in the last few days.
Alongside the southern boundary fence between DFO and the freeway there are three substantial cellphone towers in a line, perhaps 100 feet apart.
Also the building has 14 verticle billboard towers along its length that extend above the height of the building.
As seen on the video there is an extraordinarily high wall, perhaps twice as high as the building itself, on the eastern side of the complex that serves no apparent use other than as a 100 meter long advertising billboard.
These towers and structures form a 400 (?) meter long line that creates a increase in obstacle height (perhaps 50ft) right on the edge of the high embankment, to the possible salvation onto the embankment and freeway below.
Even if they had cleared the building they probably would have hit one of these structures.
Are cellphone towers and gigantic billboards essential to a modern airport?
Should they be removed immediately?
