On the question of airport capacity, the Government had established the independent Airports Commission, headed until 2015 by Sir Howard Davies. The Commission examined the nature, scale and timing of any requirement for additional capacity to maintain the UK's global hub status. The Aviation Policy Framework of March 2013 was an important piece in the jigsaw, setting out the principles which the commission would take into account in presenting its recommendations reported in 2013 and in 2015. The options included an outside possibility of a floating airport off the Isle of Sheppey.
