The Sunday Times (OZ) has a scary snippet: 'UFO' in jet crash:

KIEV: A previously unidentified flying object may have caused the deadly crash of a Ukrainian fighter into an air show crowd a week ago, the Russian NTV television company reported yesterday.

Slow-motion videotape of the July 27 accident show a dark object rising in an arc from a wood near the Lviv airfield close the flight path of the Su-27, which went on to crash into the crowd.

It was not clear what exactly the object was, or whether it struck the aircraft. The crash killed 84 and left 199 hospitalised.

Paging Pierre Salinger!
