BUCHAREST, Romania, June 6 (UPI) -- The Romanian Defense Ministry has confirmed that a fighter plane was struck by four unidentified flying objects and released a video of the incident. <br /><br />The ministry said the MIG 21 Lancer fighter plane was struck by the objects during an Oct. 31, 2007, check flight but was able to land safely, Hotnews.ro reported Friday. <br /><br />Lt. Col. Nicolae Grigorie said a video recorded by cameras onboard the plane depicts "two solid bodies, which are not translucid." <br /><br />Grigorie said authorities are working to determine what the objects could have been. <br /><br />"They couldn't be birds because there are no birds in Europe able to fly so high. And they couldn't be ice bodies because it was a clear sky -- neither could they be pieces of another plane or a meteor," he said. <br /><br />He said the government has ruled out rocket launches and ground artillery fires as causes of the incident. <br /><br />SOURCE <br /><br />UPI, "UFOs hit Romanian plane", 6 June 2008. <br /><a class="link" rel="nofollow" href="http://www.upi.com/Odd_News/2008/06/06/UFOs_hit_Romanian_plane/UPI-3559121">http://www.upi.com/Odd_News/2008/06/06/UFOs_hit_Romanian_plane/UPI-3559121</a>
