Mr. Specter. With reference to the bubble top which you have heretofore described, of what is that composed?
Mr. Kellerman. It is composed of plastic, clear plastic substance. Its use would be for a weather matter whereby the President or his occupants can see out. It is not an enclosed car.
Mr. Specter. Is it bulletproof?
Mr. Kellerman. It is not bulletproof.
Mr. Specter. Is it bullet resistant in any way?
Mr. Kellerman. It's not bullet resistant.
Mr. Specter. Could you describe in a general way at this point what efforts, if any, have been made to obtain a bulletproof clear top for the President's automobile?
Mr. Kellerman. Presently?
Mr. Specter. Presently or heretofore.
Mr. Kellerman. I am going to have to go in the present day.
