1. O n Thursday, 17 D ecem ber 1955, w hile flying near H assleholm , Sw eden, C aptain 
U lf C hristiernsson sighted an "unknow n” object. The follow ing is the translation of 
a new spaper account of the incident:
"The chief pilot of Transair, C apt. U lf C hristiernsson, and his crew  
chief, O lle Johansson, had a strange m eeting over H X ssleholm  at 1457 hours 
Thursday. A  shining m etal spherical elliptical object cam e tow ard them  
traveling in the opposite direction from  their m achine at an estim ated speed 
of sound and approxim ately 60 0 m eters below their D C -5, w hich w as on its w ay 
from  Builtofta to Broram a. It w as visible six to seven seconds; C apt. C hris­
tiernsson, w ho had good silhouette recognition, stated that w hat he saw w as 
som ething absolutely new , possibly an unm anned robot.
"The Transair plane w as autom atic controls w hen the m eeting occurred. 
C apt. C hristiernsson did not have tim e for any m easures other than to report 
to Bulltofta and the D efense Staff, w hich later sent out the follow ing com ­
m unique :
" ’The air crew of a civil aircraft observed on Thursday at 1457 hours 
over the area of H assleholm  an unknow n object m oving in the opposite direction 
from  the airplane. The object w as observed for six to seven seconds. A t that 
tim e and altitude the w eather w as clear. Because of the low lying cloud for­
m ations the object is not thought to have been seen from  the ground. The D e­
fense Staff does not know of any Sw edish plane that w as in that area at the 
tim e in question. A n investigation is being conducted.•
"Previously I have been extrem ely skeptical about all the stories of 
m ysterious objects —  called flying saucers —  that have been seen at diverse 
points, said the C aptain. N ow I don’t know exactly w hat to think; but it did 
seem  to m e that w e had seen a robot of som e kind. W hen I first caught sight 
of the object, w hich like us w as in the civil air corridor, I thought it w as a 
jet. W e had, how ever, received no w ord that any such thing w as on the w ay.
"The object cam e tow ard us at w hat I w ould say w as the speed of sound;
w e w ere flying at an altitude of approxim ately 2,150 m eters and the object w as 
around 60 0 m eters below us. It w as going in a southw esterly direction and 
disappeared after six or seven seconds.
"The object had a strong m etal shine; the crew chief, Johansson, w ho coulc 
see it longer than I, thought it w as alm ost phosphorescent. The flying w eather 
w as excellent above the clouds, w hich w ere at an altitude of about 150 0 m eters, 
and the sun w as shining brightly. The object w as proceeding just above the 
clouds.
"The first silhouette I got diagonally from  the right w as narrow . A lien 
it w as nearly directly under us, how ever, I saw that it w as nearly round, just 
slightly elliptical.
"The object, w hich could definitely not have been a m eteor, gave off no 
w aste gases or condensation traces.
"W as I afraid? N o, but curious, very curious, concluded C aptain C hris­
tiernsson.
"C hristiernsson has seen just about everything in aviation and has very 
good silhouette recognition. F rom  1942 to 1946 he w as a volunteer serving in

the Royal A ir F orce. H e finished as a captain in the British A ir F orce, after 
m aking som e thirty raids in a M osquito against enem y territory, in both N orth 
A frica and Italy.
"A ir F orce C hief, G eneral N ordenskiold, announced that it had been ascer­
tained that the object could not have been any Sw edish aircraft.
"•W e are now investigating,’ he continued, ’w hat our radar stations m ight 
have spotted.* "
2. C aptain C hristiernsson is U i years of age and w as born in SkSne in the southen 
part of Sw eden. A n extrem ely reliable source in the Royal Sw edish A ir Board, w ho w as 
born in the sam e tow n and w ho is a life-long acquaintance of C apt. C hristiernsson’s, 
has stated that C hristiernsson is charm ing and w ell-liked, but that he is also m ost un­
trustw orthy and w as dism issed from  a form er position for "financial difficulty". D ur­
ing the last w ar, C hristiernsson tried to take a Sw edish A ir F orce B-18 and fly to Eng­
land, but w as intercepted at G othenburg and w as put in jail. A lthough it is generally 
agreed in the Sw edish A ir F orce that C aptain C hristiernsson is one of the best (and 
m ost discussed) pilots in Sw eden today, he has never served w ith the RSA F  except as a 
reserve captain.
3. A lthough the source above personally doubts C hristiernsson’s story, the new s­
papers report that the D efense Staff is continuing its investigation of the incident.
