An appeal to finance a second air ambulance to cover north and mid Wales has raised £40,000 since its official launch in February.

The Welsh Air Ambulance Charity needs to raise £750,000 a year to fund the emergency service.
If £250,000 can be raised by July, a second air ambulance could come into operation in time for the busy summer season.
The first Wales Air Ambulance, which is based in Swansea was launched in March 2001.
It has already flown more than 800 missions, mainly in south and mid Wales, and has helped more than 400 seriously ill or injured people.
Currently, the North Wales Police helicopter is sent out to attend serious incidents in the region.
The force has a fully-trained paramedic onboard.
Air ambulance appeal organisers are set to hold a mini-launch in Wrexham and Flintshire later this month.
Appeal manager Julie Hinchliffe said they have raised £10,000 from local councils alone.
"We mailed every community council in Wales and I am delighted to say that the response across the country has been wonderful," she said.
The helicopter is sent out to serious road accidents
"We've raised over £10,000 to date and the cheques are still coming in.
"People are finding all sorts of ways to support us.
"It doesn't matter who you are or where you live - there may well come a time when you may need the services of the air ambulance.
"I think this is the realisation that is fuelling people's enthusiasm."
The Wales Air Ambulance has recently changed its livery from yellow to red and green.
Mark James, one of the charity's trustees said: "We're well aware that people were used to a yellow helicopter, but the routine service meant that we had the opportunity to change the colour scheme for free.
"I believe that we've now got the best of both worlds.
"We match most of the other air ambulances in the country and the darker colour means that other aircraft should be able to see us more easily."
