Target: Enlightenment

Barbara Clegg, one of the very few women Targeteers (Targetrixes?), at the helm for this adaptation.

The first time the yacht pitches, Turlough thinks he's in an earthquake or a landslide.

Tegan knows that the 'camera' for the TARDIS scanner is in the light on top of the roof.

The fo'c'sle is full of tobacco smoke - I thought smoking below decks was strictly banned on wooden ships? The Doctor remarks that it's lucky Tegan didn't come with them - a woman below decks would have started a riot. Cut to Tegs in the hold - the narrator remarks that that isn't a very comfortable place for a woman either. 'Particularly when someone is following you,' thinks Tegan, bizarrely completing the narrator's thoughts.

The Eternals - even Striker - are completely motionless when first seen. We see this interesting phenomenon occasionally throughout the book.

The companionway to the deck is a ladder, not a staircase.

The sight of Venus makes the Doctor remark that it is aptly named after the goddess of beauty.

There are more details about the objects in Tegan's cabin, including the fact that Aunt Vanessa was Tegan's favourite aunt.

Turlough goes into more detail about the solar wind. Jackson doesn't interrupt the conversation - the whole bit about the key to the rum locker is missed out, as is the reference to it later in the wheelhouse.

'The Buccaneer' is actually the name of Wrack's ship. I didn't pick that up from the episode, I thought the references to it were just generic - 'the buccaneer [ship]'.

Mansell (Leee John's character) is described as having 'the lithe power of a black athlete'. When he throws Turlough at Wrack's feet, he orders him 'Lick the Captain's boots!'

The wine that Wrack offers Turlough is muscatel, and their conversation appears to take place in private. She rhapsodises about how she came by the memory of the taste of the wine.

Turlough thinks that people exposed to vacuum explode immediately. Perhaps he wasn't listening in his Tryon science classes.

When Tegan flounces off to change out of her party dress, the Doctor and Marriner exchange a look which seems to say 'Women!'. Early anticipation of the 'human Doctor' idea perhaps.

It's 'becalmed' that Mansell says to Wrack, not 'be calm.' He's telling her that Striker's ship doesn't have enough wind to move.

When the White Guardian talks about 'allocating a share' of Enlightenment to Turlough, he takes on the tone of a company chairman.

The 'Enlightenment was not the diamond. Enlightenment was the choice' line is mangled by the insertion of 'Simply a lump of carbon!' into the middle.

After the White Guardian disappears, the stateroom of the ship starts to fade away around the TARDIS crew.
