History: London Then And Now, 1897-2012, England, United Kingdom

Stansted Airport, situated north east of London in Essex, is the main UK hub for Ryanair and Luton Airport to the north of London in Bedfordshire, caters mostly for low-cost short-haul flights. London City Airport, the smallest and most central airport, is focused on business travellers, with a mixture of full service short-haul scheduled flights and considerable business jet traffic.
Roads
Although the majority of journeys involving Central London are made by public transport, car travel is common in the suburbs. The inner ring road (around the city centre), the North and South Circular roads (in the suburbs), and the outer orbital motorway (the M25, outside the built-up area) encircle the city and are intersected by a number of busy radial routes—but very few motorways penetrate into inner London. The M25 is the longest ring-road motorway in the world at 195.5 km (121.5 mi) long.
