In a minute well hear from the boss of microsoft, what hes doing top make his company cool again. But first, Monarch Airlines has been placed into administration and all flights from the uk have been cancelled and will not be rescheduled, accountants kpmg said. The announcement leaves 300,000 future bookings cancelled. The Civil Aviation authority has said it had launched a programme to bring 110,000 Monarch Airlines customers back to the uk. Joe lynam has more. This is a very worrying news for the 100,000 or so monarch Package Holidays passengers. They will be brought home courtesy of the atol protection scheme. What about the bigger airline . There is a risk that customers and supplies will lose faith and confidence in the ability of monarch to pay its bills. There is still time to keep the Airline Business going while losing the atol licence. A wider problem is there are too many seats and not enough bums to put on them. By now it looks as though the monarch package business is the latest victim of that. Catalonia has voted to become independent from spain in a controversial referendum which was not sanction by the Spanish Government. According to catalan leaders 90 percent of voters wanted a separation. But its reported there was only a 40 turnout. The spanish Prime Minister says the referendum didnt happen, more on that in a moment. As well as a distinct history dating back almost 1,000 years, economic forces have also spurred the desire for independence in the region. It is one of spains wealthiest regions, making up 16 of the National Population and accounting for almost 19 of spanish gdp. But there is a widespread feeling that the Central Government takes much more than it gives back. According to 2014 figures, catalonia paid 9. 89bn euros more into spains tax authorities than it received in spending the equivalent of 5 of its gdp. Meanwhile, state investment in catalonia has dropped in 2003 the National Budget allocated roughly 16 of investment to catalonia but by 2015 that had dropped to 9. 5 . So if catalonia does actually leave spain it would have a huge impact on one of europes biggest economies which is currently on track to grow by 3. 1 this year. Recovering from the recession and the financial crisis. With me is dr Pablo Calderon martinez, lecturer in spanish Politics Aston University what happens next . It is a bit of a mess. It is indeed. I suppose the cattle and government is going to declare independence soon and we will have to see how the Spanish Government reacts. I do not think they will take it very well but i think negotiation is the only answer. If you are independent are suppose you raise taxes but what is the first thing you do . The proof of it . First of all you have to seek this is a big issue seek recognition from other countries. They will struggle to that, certainly in europe and internationally as well. The European Union has been very much offering support for the Spanish Government but obviously condemning the violence but i think they would find it very, very hard to support any independent catalan state. This will be discussed purely in political terms for the next few weeks but beneath it is an economic story and it is important. It comes out of this huge recession, that spain has been through. To a great extent this is an economic movement, an economic nationalism of sorts. That is not to say that catalan does not have its history and culture but it comes as a reaction of the economic crisis and the financial crisis, this sense of injustice that somehow catalonia pays more to spain. You can put it in the same basket is brexit, and president trump, it is popular reason in a way . Popular. Trump, it is popular reason in a way . Popular. In spain it seems more of a political crisis. Lack of representation. The solution is political dialogue. Will it affect the economic recovery . political dialogue. Will it affect the economic recovery . I think so. It will create uncertainty. Spain is relying on investment and i think any more trouble of this sort is going to threaten the recovery in spain and it is not good news for catalonia or spain.

The answer might be moisture. It is counter into it it but that is what i believe could be the situation. Over time, rain and humidity can get trapped in the insulate thing fire. In a fire this moisture is released to steam. Steam generated from the burning foam impinges on the aluminium. It can generate hydrogen is supplying steam near fire at such a rate is to be able to react with hot aluminium but not start to put it out.
