to Omniport, whilst retaining the remaining 19.9%. Omniport has also acquired 100% of Norwich Airport Travel Ltd. Since the sale to Omniport the airport became one of the UK hubs for budget airline Flybe and the number of flights and destinations served increased. In 2005 a £3.5 million terminal expansion programme began. In 2009, during filming of the BBC show Top Gear, operations from the airport appeared to be disrupted when a caravan, adapted into an airship and flown by James May, drifted overhead the airport, infringing its controlled airspace. In reality, the event occurred after much pre-planning between the airport authorities and the BBC; and scenes showing the airship in the airfield boundary were actually filmed after it had lifted off from the airfield to satisfy the requirements of the film crew. In 2007, the airport introduced its Airport Development Fee (ADF). All passengers over 16 departing from the airport pay a fee of £10. The airport was sold in 2014 by the majority stakeholders of Omniport to the Rigby Group, who integrated the airport as part of Regional & City Airports in April 2017. Recent developments Norwich International Airport announced in 2015 that four new routes were being considered for Department for Transport (DfT) funding. The routes being considered included: Dublin Airport (Flybe, double daily return weekdays, single return weekends), Paris Charles de Gaulle Airport (Flybe, daily return), Newcastle Airport (Links Air, double daily weekday return), and Exeter Airport (Flybe, daily return). Links Air proposed a start date of 1 September 2016, but the airline was put into liquidation. In November 2015 it was announced that bids for routes to Newcastle and Exeter had been successful, with the inaugural flight to the latter on 24 March 2016, operated by Flybe. Flybe also confirmed plans to operate summer sun and winter ski routes from Norwich Airport as part of a five-year deal with the Regional & City Airports (RCA) group. From May 2016, one of Flybe's Embraer ERJ-195 aircraft began operating multi-weekly flights from Norwich to Alicante and Málaga. In 2016 an engine test facility opened on site. The KLM UK Engineering Academy opened on 18 April 2017. On 6 July 2017, Managing Director Richard Pace announced a 30-year vision to treble passenger numbers at the airport. The plans include raising annual passenger numbers to 930,000 by 2030, and 1.4 million by 2045, forging new routes to Paris Charles
