Friends and family of the pilot killed in the Glasgow helicopter crash have gathered for his funeral.
Captain David Traill, 51, was one of nine people who died when the aircraft crashed on to the roof of the city's Clutha bar on Friday last week.
Before the memorial at Glasgow University, police officers, air ambulance pilots and paramedics formed a guard of honour.
Mr Traill, originally from Falkirk, was a former RAF pilot and instructor who served in both Gulf wars before taking on the role of civilian pilot for the Glasgow-based Scottish Air Ambulance and Police Scotland.
The coffin was carried in to the university's Bute Hall with a large bouquet of white lilies on top.
Deputy First Minister Nicola Sturgeon joined uniformed RAF officers, emergency services workers and senior police officers at the service.
The technical problem affecting the Swanwick air traffic control centre is unlikely to be fixed before 2pm.
Thousands of people have been affected by delays at major airports including Stansted, Heathrow and Gatwick.
The Association of British Travel Agents (Abta) said: "Technicians are working to try to resolve the issue but have advised that this is unlikely to be before 2pm today.
"Delays and flight cancellations at some UK airports are being experienced as a result. Customers due to travel today should liaise with their airline to establish if there are any changes to their flight arrangements."
The association said customers should be prepared for potential delays and advised them to carry essential items such as medication in their hand luggage.
Daisy McAndrew, who is stranded on a plane at Gatwick, said passengers had been "given no indication" of how long it would take to solve the air traffic control problem.
David Cameron has said his thoughts are with everyone affected by the floods after one of the worst tidal surges in 60 years devastated parts of the east coast of Britain.
My thoughts are with everyone affected by the floods - I know the emergency services are doing a great job helping out.
Communities are beginning to count the cost of the damage after thousands were finally allowed to return to their homes yesterday.
David Cameron has hailed a "historic" global trade deal which he said could be worth £1 billion a year to British businesses.
The World Trade Organisation (WTO) secured a deal to lower barriers and speed up customs procedures after overcoming late objections from India and Cuba.
"I am delighted that we have secured an impressive global deal worth over £1 billion a year to British businesses and £70 billion globally. This deal will help boost our exports, meaning that UK companies can grow and employ more people.
"If just 100,000 small businesses either start exporting or spread to new markets over the next five years, this would generate an extra £30 billion for the UK economy and create 100,000 new jobs.
"By slashing barriers to trade, this deal will also provide a lifeline to the world's poorest people."Helping developing countries to grow is not only the right thing to do, but it also increases potential markets for us all.
"So this really is win-win and the World Trade Organisation is to be commended for this historic deal."
A scintillating performance from Australian bowler Mitchell Johnson left England on the brink of another defeat in the Ashes series.
England were all out for just 172 on day three in response to Australia's 570 for nine declared.
Mitchell Johnson once again ripped through England's line-up taking seven for 40.
With England's batsman already under pressure after a poor performance in the opening test in Brisbane, only Ian Bell and Michael Carberry emerged with any credit who both contributed half-centuries.
England will have to dig deep to avoid falling 2-0 down in the five-match series, with the hosts extending their lead to 530 after closing on 132 for three in their second innings.
