I'm like the second plane that made the tower's face off
That shit that let you know it's really not a game dog

from Yasiin Bey – Close Edge Lyrics on Rap Genius

Meaning

A reference to the September 11 attacks on the World Trade Center. It was the second plane that made it clear that New York was under a terrorist attack (until then some thought that the first collision was just a tragic accident).

Mos Def is like rap’s version of the second plane. When you see him you know you’re dealing with serious business.
