Doctor Who: Storm Warning

After a dangerous encounter in the space/time vortex, the Doctor finds himself on Earth, October 1930. Or rather above it, aboard the British airship R101 on it's maiden voyage over France. Also on board is a young stowaway, Charlotte 'Charley' Pollard, seeking adventure and excitement away from her stifling family atmosphere. What Charley doesn't know, but the Doctor does, is that the flight is destined to end in tragedy, although no one really knows why. Not even the Doctor, although maybe the passenger in Cabin 43 can help.
