METAL FRAGMENTS O SERVED AT WEST RUDGE, NE11 HAMPSHIRE, JULY 7, 1947
SECURITY MA.Tr.ER (X
7-29-47
Referenoe is made to Boston teletype to tho Bureau datod July 18, 1947.
Dean John M. Bunker, the original inf'or111ant, baa advi:sed that a speotographio
examination has boen oomplotod of tho metal partioles referred to. Thay were
determined to be of ordinary oast iron whioh bad boen aubjeoted to a very
high degree of heat. The heat caused aoales to be formed on the oaet iron
whioh were originally thought to bo of some metallic alloy.
The soientist examining the partioloa oonoluded that if they had oome through
the air from any great altitude in as small pieoea aa they were found th.en
most of the heat would have been taken from them by the time they reao~ed
the ground and fires 'WOUld not havo resulted. It ia noted they landed
approximately 700 feet from a railroad traok e.nd inquiriea were oonduoted by
MI'!' to determine whether or not the partioles oould havo been originally a
pa.rt of a liuer in a smoke staok or some other part of the steam engine.
Theee
inquiries resulted in positive information -that the particles did not oome from
a train or looomotive. Measurements of the four pieoes examined revealed
that they had most likely been originally all part of one hollow oylinder,
eight inohes in diameter and three sixteenth• of a.n inoh in thioknesa. It
felt that ono piooo falling from a great height would haw still retained
a good part of its heat and probably 11ould have mashed when 1t hit the ground.
A aoiontiat, whom Doan Bunker did not identify by name, recalled that oast
iron oylindors of similar measurements had been used in New Mexioo on
roaearoh work on a guided missile projeot. However, this unidentified scientist
not so oonoludo to the exoluaion or all other possibilities.
OONP INi'T, '"
