I was just watching the "Meet Kevin Johnson" episode online (ABC.com),
and I caught this out of the corner of my eye.
In the scene after Michael gets out of the Fiji taxi and puts on his
hat in front of the Kahana, there is a plane flying in the
background. Right when it's about to exit the screen in the upper-
right corner, it looks like there is an explosion above one of its
wings (section 3 at 25 minutes and 25 seconds, if you want to look;
you can see it best in the Full Screen HD mode).
At first I thought it was just light reflecting off of the plane, but
after rewinding it definitely looks odd.
