Doing some research on AFDs it appears that the first thought screen helmets were made in 1998 and used aluminum foil. They were sent to Dr Feynmann in Iowa. The investigator reported that one user tried it for a short time with no results. Afterwards, the investigator could not be reached and the whereabouts of the helmets are unknown.
About 8 thought screens were made in early 1999 using a metalized plastic which is used in static shielding bags. Six users reported success but two users were overcome by telepathic commands from the aliens, removed the helmets and were taken.
From 1999 to 2004 about 50 people abducted by aliens have reported using thought screen helmets and hats made with Velostat. Since 1999 only two abductees were taken when they wore thought screen helmets with Velostat. Most of the other abductees using thought screen helmets reported success. Some abductees could not be reached after they tried their thought screen helmets.
The development of new prototypes is still being conducted all over the world. Thought vibrations were photographied and produced in different patterns (see a smoke ring type of thought).
Most of my work as design engineer is against fixed timetables, and my clients are desperate to have their designs before the Hagim, the two week period of religious holidays (Yom Kippur and Rosh HaShana) when all the public bureaus are closed and Israel stops working. Under such a stress, my mind is desperate for distraction and a reason to avoid work. In short, I have to design an effective thought deflector helmet NOW. It is a mission that cannot be delayed or postponed. Mr Ayzik is phoning every five minutes asking anxiously if and how I am advancing with his project, but I have no choice. I must focus in this urgent and most important problem NOW.
