In order to help you understand the arguments surrounding airport expansion in the UK you need to read some of the background documents. The UK government has set up an Airports Commission specifically to make a decision about airport expansion and they have collected some useful evidence and drawn some interesting conclusions. You should read the following documents before the end of the week.
The Commission has published a report explaining why new airport capacity is needed and why the new runway will need to be at either Gatwick or Heathrow.
The Commission also published as assessment of a new airport in the Thames Estuary, popularly known as “Boris Island”, and explained why they felt it was untenable.
These two documents contain vital information which you will need to be able to write a competitive essay, so read them carefully and be prepared to discuss them during lessons.
