I just finished watching them go! It was fun. Two palms web cam goes by very fast!
First frame entrance it is listed as 17:24:50
the last frame I got it is listed as 17:25:30
The picture only changed 3 times so have your sister waiting!
On the cape canaveral web cam, I got a picture of it at 17:12 and then again at 17:19
Good luck! I am going to ask my friend to try and get the picture too! Hope it works.
