People have been reporting UFO's and there occupants. But, what about there gadgets. How many UFO encounters involve the use of "tricorders," "Phasers" and other exploratory tools. Except for the abuction reports where the abductees are in the spacecraft. How many aliens have been seen outside there craft; or anywhere, with tools or other devices? Have there been any known accounts of devices or tools recovered from reported landing sites? Don't these aliens ever drop anything?

There are many cases of people seeing occupants analyzing soil and taking samples using tools. Many of the cases are from the 1950s, when a lot of the UFO reporting centers did not want to be bothered with aliens thinking it is too controversial.

Many abductees also report being examined with tools and instruments, too.

Many books mention these cases, with Richard Dolan's UFOs and the National Security State Vol 1 being one of them.
