In a plane.
"In fifteen minutes we would be landing at the Dulles International Airport."
The voice over the plane's in-built speakers came on. No doubt that was the pilot.
The Professor shot Ella a glance then looked away. She didn't seem to be in a good mood. She hadn't been since yesterday. And they were lucky to had been able to find a free plane traveling their way.
The plane was well occupied. They had been told when they had driven to the Murtala Mohammed Airport in Nigeria, that since the alien machines really affected the world, people have been given choices to migrate to several countries of their choices.
At first, the Professor had thought it to be some silly mind games. Until they got to the airport and found several planes and several people struggling to get in.
