Serious produce server Neser Balwich directs from the front seat while aerial cameraman Mike Calen controls the camera attached to the lows. Above 10,000 feet, the pilot must breathe oxygen through a passed tool beneath the nostrils. Approaching the crater, conditions do not look good. Today, Alps is spurting out steam and gases making flying extremely risky. Up here, the air is so thin, the helicopter cannot hover and must keep moving. This is aerial filming at its most extreme.

The team have to seek the rare opportunity to see into its molten heart. But now they must be sent to safety.
