                                            The alien craft are called looking glasses.  There are 9 of them in the USA with 112 throughout the world.  There are other spaceships in orbit around the Earth. | 
                                            They are called Shells.  There are 12 of them in various places throughout the world. |

                                            The Looking Glasses are about ten by twenty feet and rest on the ground inside of a large tent the military erected around it. | 
                                            The Shells are hundreds of feet high with a door on the bottom that opens every 18 hours to allow visitors to enter.  The persons entering wear protective gear in case the aliens do not provide a proper atmosphere for humans.

                                            The Looking Glasses transmit an image to the humans when the heptapods activate it.  The humans are not afraid of them. | 
                                            The heptapods are actually inside the shell and appear to float/swim/stand in a liquid.  The humans entering the Shell are frightened at first but eventually calm down. |
