Claim:
1. An aeroplane comprising an external skin and an internal bulkhead delimiting a cabin, and comprising an escape opening passing through said external skin and said internal bulkhead, said escape opening being closed off by an external escape hatch that is movable between a closed position, in which the escape hatch is disposed flush with the external skin, and an open position, said external escape hatch comprising locking/unlocking means that are controlled by an external opening controller, the aeroplane further comprising: an internal escape hatch that closes off said escape opening flush with the internal bulkhead; at least one catch movable between a locked state and an unlocked state, said catch keeping said internal escape hatch in a closed position in the locked state; a first opening controller configured for controlling the passage from the locked state to the unlocked state of the catch being accessible from inside the aeroplane; a second opening controller configured for controlling the passage from the locked state to the unlocked state of the catch being positioned such that the actuation of the external opening controller of the external escape hatch or the passage of the external escape hatch from the closed position to the open position causes the second opening controller to be actuated; wherein the internal escape hatch comprises pressure regulating means which automatically trigger the opening of said internal escape hatch when a pressure difference on either side of said hatch exceeds a given value.
