"Computerised Airliner" joke

The world's first fully computerised airliner was ready for its
maiden flight without pilots or crew. The plane taxied to the
loading area automatically, its doors opened automatically, the
steps came out automatically. The passengers boarded the plane
and took their seats.
The steps retreated automatically, the doors closed, and the
airplane taxied toward the runway.
"Good afternoon, ladies and gentleman," a voice intoned as the
airplane lifted off. "Welcome to the debut of the world's first
fully computerised airliner. Everything on this aircraft is run
electronically. Just sit back and relax. Nothing can go
wrong........ nothing can go wrong...... nothing can go
wrong......"
