Dr. Johan Bäckman of Lund University, in Sweden, who used radar to track 225 birds, says that “even the most advanced planes, with very good navigational instruments would probably be unable to judge the wind drift like this. ”
Dr Johan Bäckman Rootsist Lundi ülikoolist, kes jälgis radari abil 225 lindu, ütleb, et „isegi kõige paremad lennukid, millel on väga head navigatsiooniseadmed, ei suuda hinnata tuulest tingitud triivimist nii nagu linnud ”.
