I think we're being followed...
I was on a ride along with a very cool LAX airport operations guy. He was called on to escort a FedEx MD10 Aircraft that needed to taxi from one side of the airport to another. An escort was required since a mechanic was behind the controls and an active runway had to be crossed.
When I looked at the aircraft in the side mirror, I started laughing at the "Objects in this mirror are closer than they appear" text you see in the picture. It reminded me of that scene in Jurassic Park where the T-Rex was chasing the Jeep. That aircraft looked huge!
