This is the terrifying moment an enormous articulated tanker launched into the air at high speed across the path of a driver and exploded into a ball of flames.

The incredible footage was caught by chance and posted online by

Benny Wright, whose disbelief at the freak incident happening before his eyes is unmistakable.

Travelling in a vehicle with another man, and by chance filming the road ahead, the enormous tanker suddenly appears from the left, charging along at high speed.

The out-of-control vehicle launches completely off the ground, 'flying' over the road they are driving on, in front of their eyes.

'What the!' says one of the men in the vehicle.

The entire tanker is in mid air for a brief moment before is crashes and ploughs into grassland exploding into a fireball.

An enormous mushroom plume of black smoke billows into the air as the tanker comes to a halt.

As an inferno rages in the tanker's path, the stunned drivers come to  halt.

One of them says: ''I got him on camera... I'm going to go see if he's alright.'

He is then seen running in the direction of the fireball. It is not known what the outcome of the crash was.
