MOTORISTS driving along the M4 in Slough were treated to a rather unusual sight this afternoon, Saturday.

This was in the form of the huge top half of a 737 plane as it was transported using the motorway on its final journey.

One person believes the plane could be a retired Air France a318 plane.

A resident said: "Wow this is not something you see everyday a plane being transported on the motorway."

Highways vehicles were spotted surrounding the plane as it was making the journey along the M4 motorway.

The M4 motorway is close to Heathrow Airport, so it's not unusual for the plane to set off its journey from there.
