We were being vectored to the ILS Runway 8 at Burbank (BUR) just outside of BUDDE intersection at 3;000 feet when the flight attendant (who was sitting in the jump seat) described what she believes was a drone fly past us. The flight attendant estimated the object was at our exact altitude and about half a wingspan off to the left of our aircraft.Neither the captain nor I ever saw it. We continued for an uneventful landing on Runway 8.
GIV First Officer is informed by the Flight Attendant in the jumpseat that they had just missed a drone at 3000 feet during vectors to Runway 8 at BUR. The flight crew never saw the UAV and no evasive action was taken.
