text: It started life as Castle Donington Airfield - a decommissioned RAF base, and now handles 4.5m passengers a year.
  An estimated 95m passengers have passed through the airport since it opened on 2 April 1965.
  In 1963, it was bought for £37,500 by a committee of representatives from Nottinghamshire, Leicestershire and Derbyshire as a replacement for Burnaston Aerodrome near Derby, which later became part of Toyota's car factory.
  Work started on the £1.37m airport in 1964. In its first year, 114,000 passengers passed through the airport, which now sees 4.5m passengers a year.
  The first destination on offer was Glasgow but it now flies to more than 70 locations as diverse as Aberdeen and Barbados.
  A runway was extended in 1970 to accommodate bigger aircraft but the first Boeing 757 did not arrive until 1982.
  Since it was officially opened by the Duke of Edinburgh in 1965, it has had its fair share of royal visitors, including the Queen Mother in 1977 and Princess Anne who opened a £3m passenger terminal in 1986.
  In 1989, disaster struck when a Boeing 737 tried to make an emergency landing at the airport but crashed on the M1 motorway at nearby Kegworth, killing 47 people.
  Mercifully, no one was killed on the ground and 74 passengers and crew survived.
  A £14.5m new departure building opened in 1996, when the airport welcomed its 25 millionth passenger.
  Managing director Andy Cliffe said the aviation industry had changed "enormously" in the past 50 years, with the proliferation of low cost carriers.
  Derby Airways was the first company to fly from East Midlands. The firm later became British Midland which operated at the airport in the form of low cost airline BMI Baby until 2012.
  In 2004, Ryanair began operations and the airport introduced self service check-in.
  The airport hit global headlines in 2010 when a suspicious package discovered on a Chicago-bound cargo plane was found to contain explosives.
  The package, which was a printer toner cartridge with wires attached, was addressed to two Jewish places of worship in the city.
  East Midlands, which employs about 7,000 people across its entire site, is the UK base for carrier services DHL, TNT and UPS and is the main air hub for Royal Mail.
  The airport, which is owned by Manchester Airports Group, is the busiest cargo airport in the UK, shifting more than 300,000 tonnes a year.
  "Our long term plan is to grow to about 10m passengers and 1m tonnes of freight. We're ambitious for our future," said Mr Cliffe.
  A £12m terminal redevelopment is about to be completed at the airport
  The anniversary was marked with a party on Thursday and a time capsule will be created later this year.
