The aeroplanes landing in Gibraltar's airport bank around that famous rock. Negotiating strong cross winds, they glide onto a runway that intersects with a road - an infamously tough landing that's an exercise in managed risk.
And in an enclave of heat-baked, low-rise offices in this UK territory, there has been a boom that has lasted 13 years, as 'Gib' has become one of the most concentrated online gambling industries in the world, employing 2,400 people in a territory with a population of 29,000.
Online gambling companies went to Gibraltar, Malta, the Isle of Man and Alderney in the early 2000s, lured by advantageous tax regimes of under 1% per bet, as opposed to the UK's 15%.
Now Britain wants that revenue back. The Government's Place of Consumption (POC) Tax, due to take effect next year, requires online gambling operators to secure a UK licence, so tax will be paid where the customer is, not where the server is.
Thus has British gambling joined the conversation started by Facebook and Amazon about offshoring tax - hence the POC tax.
'The Treasury reckons it will raise £300m in the first year,' says Warwick Bartlett, CEO of Isle of Man-based gambling consultants GBGC and a seasoned industry observer.
Certainly, the gains are plain to see, as in an otherwise flat economic scenario, gambling looks extremely strong, and is ever more visible.
In April, the Coates family, who run bet365 - one of the world's largest online sport betting sites - were mooted to be the UK's first gambling billionaires, with a business worth about £800m just 13 years after they launched the firm.
Betfair, the influential betting exchange set up in 2000, recently rejected a £920m bid from private equity firm CVC Capital Partners as not good enough. And in the latest Sunday Times Rich List, Britain's top 10 internet betting tycoons are each valued at more than £100m. Why wouldn't the Treasury want some of the action?
The gambling industry has enjoyed an impressive counter-recessionary trend, particularly online.
In 2008, the UK online sector was worth £1.27bn. By 2012, this was £2bn. The key factor is smartphones and tablets. Juniper Research estimates that betting on mobile devices alone will be a $100bn worldwide industry by 2017 and you'll be able to gamble on the bus or train, even on planes.
As gambling consultant Steve Donoughue says: 'The buzzword is "ubiquity".'
Donoughue, who is doing a PhD in betting, thinks we're in the second great phase of online gambling. 'Five years ago, I was doing a mobile gambling conference,' he says. 'They were going on about WAP. I said: "This is bollocks. It's going to change out of all proportion." And it has. On a normal Saturday William Hill posts six million bets. That's more activity than Nasdaq.'
The tipping point became apparent last year, he says. 'It's now all down to the 'second screen' - the TV and smartphone/tablet combination - and you access betting in your living room.'
All those advertisements wrapped around televised sports are part of what the industry calls 'bet-in-play' - real-time betting as you watch - which is growing fast. As a spokesman for bookmakers Ladbrokes puts it: 'The fundamental thing in gambling is to add excitement and with bet-in-play the odds flex as the action unfolds. It's major.'
And we're nowhere near the peak yet, adds Donoughue. 'Next we'll have the cheap 4G phase, possibly within the next few years.'
After pornography, gambling is driving internet technology and usage, and the next great gambling shift will herald 'very cheap, very big televisions', as Donoughue puts it. 'So this is the scenario. I'm in my flat with a 100-inch TV on a terabyte connection and lovely Svetlana is enticing me into a betting shop.'
On Britain's high streets, real betting shops have managed to survive, mainly by bringing in gaming machines known as fixed-odds terminals. 'But I fear that betting shops and their customers are dying,' says Donoughue.
The key business action is online and the big high street players - William Hill, Ladbrokes, Coral, Paddy Power - have been joined by online giants Betfair, Bet365, Zynga and 888, with further newcomers from the tech world.
Now money (as opposed to fun) gambling is starting to blend with social media. Last year, Facebook launched its first money gambling game, Bingo Friendzy, and in the US, Chris DeWolfe, a co-founder of Myspace, is launching a gaming studio with investment from Jeff Bezos of Amazon and Eric Schmidt of Google.
'Everyone is really expecting this to become a huge business,' said DeWolfe.
As part of this surge in betting, any odds are possible. Horse racing is a diminishing part of a gaming landscape that ranges from sport - football, cricket, golf - to bingo to online casinos, as well as increased betting on reality TV shows such as The X-Factor and The Voice.
There's consumer betting on the price of assets such as shares and commodities plus, as Ladbrokes's spokesman says, 'a rise in bespoke and "small books".
There was a big interest in the papal contest, for instance, and consistent interest in the Booker and Turner Prizes.'
The name of Will and Kate's baby is currently popular.
And the opportunities keep on coming, with one big prize: the relaxation of online gambling in the US. Already generating $32bn annually in the US, it is set to soar as 12 US territories seek to liberalise their laws, and UK investors are mustering, along with casino operators.
MGM Resorts and Boyd Gaming Corp have arrangements with Gibraltar companies Bwin.Party and 888. Rational Group in the Isle of Man, which operates real-money big-hitter PokerStars, has acquired the Atlantic Club Casino Hotel.
William Hill already has licences in Nevada. 'Plus the EU and the US are talking about renegotiating the trade agreement,' says Bartlett. 'Gambling will come up. It has to.'
The point is that many countries actively encourage gambling. 'I set up Malta as an internet gambling jurisdiction and asked them: "Why do you want to do this?"' says Bartlett. 'They said: "Jobs. We don't want our children to leave Malta." They expected 500. Within two years there were 1,000 jobs, then later, 5,000. All high-paid, white collar.'
It's the same in the UK. Bet365 supports about 1,700 jobs in Stoke. Betfair has 2,260 in London. And at betting shop level, too, the industry provides thousands of jobs that it would be folly to lose.
Despite this, gambling has never had a good image. 'As a sector we realise we're not everyone's cup of tea,' says the spokesman for Ladbrokes. 'But there are very few people who don't want the sector to exist. It's not akin to tobacco. We are tolerated.'
Now, as the market leader in online gambling, Bartlett thinks our firms and expertise should be celebrated. 'It's important for gambling companies to have a presence here for the same reason as the City,' he says. 'You can do business in the east and west the same day. The software and marketing is excellent which is important. So you need a presence in the UK.'
And contrary to expectations of tech supremacy, the Americans are way behind. 'It sounds incredible,' says Bartlett. 'But they still don't understand online gambling, because it was banned. We've got it right. Our IT infrastructure is superb and payouts have never been higher. There's lots of competition - 146 casinos, 600 bingo halls, 30,000 lottery outlets, 8,700 betting shops. The customer has never had it so good. And illegal bookies don't stand a chance.' Are there any constraints? 'Not really.'
A BETTER BREED OF BETTOR
Among City traders, gambling is prevalent. 'A high percentage of my colleagues have a flutter and a few of the guys even own horses,' says Damon Bailey, 34, who works in an long-established brokerage firm in the City. 'It goes with the territory. If you take risks in your daily job, then you'll probably take them in your leisure time.'
'I'd characterise my betting as intermittent,' he says. 'I like to have a flutter online but I'd never go into a betting shop. So if it wasn't for online, I probably wouldn't do it. I don't want to go to the betting shop and it's about the ease of access in the internet. Online has changed everything.'
Bailey sees gambling as part of his leisure life; harmless enough. 'I work hard and play hard. Classic.' He takes part in consumer-end financial spread betting ('after all, it's related to my job') and also sport betting, including bet-in-play (the real-time betting activity exemplified by Ray Winstone's grating advertisements for bet365 ('Bet in play. Nar!').
He uses the Betfair exchange for its 'better odds' and says that betting 'makes sports more interesting'. Bailey sees no problem at his level of gambling.
'I'm habitual but in no way an addict,' he says. 'I like big sporting fixtures and, as well as betting online, I go to race meets. At work we have pretty challenging days so it's a kind of relaxation.'
And as he says, if you keep your wits around you, you'll end up better off. 'I have deposited £1,631.79 and withdrawn £2.631.79, so I'm a grand up.'
Some will remember the fuss under Labour about super-casinos. 'Labour thought gambling could grow,' says Bartlett. 'But the Daily Mail, the Guardian and the BBC didn't like it, and Gordon Brown said we don't want more casinos and put the tax up. More recently, a select committee had a look and said that the opportunity has gone.'
Now we've lost out, as gambling could have been positioned as part of the hospitality industry.
'In Spain, Las Vegas Sands is spending $35bn on a casino and entertainment resort outside Madrid with no tax, no smoking ban, and the Spanish said: "OK. We want money and jobs,"' says Bartlett. 'The Galaxy in Macau has a beach, three hotels, shops, restaurants and a cinema. The Venetian in Macau has a 15,000-seat indoor stadium.'
With its agenda for growth, the British Government should take heed of such enterprises, he reckons. So why won't we do it?
'We need more employment. So when the papers produce anti-gambling arguments we say: "Go tell people on the dole." The catalyst for gambling deregulation is recession.'
Gambling has been legal and available on the high street since 1960 and online since 1995. But something about the isolated nature of online gambling bothers critics. The UK's chief scientific adviser, Professor Sir John Beddington, recently warned that online gaming was changing people's views of themselves and even threatened 'community cohesiveness'.
Dr Abigael San, a psychologist who has worked with problem gamblers, is similarly concerned. 'Its ubiquity bothers me,' she says. 'It's certainly increasing in my practice, particularly with people in their 20s. The problem with online gambling is that it doesn't feel real.'
It's easy to get in and hard to leave.
The industry disagrees. 'There's no evidence that online has increased the percentage of problem gambling,' says Ladbrokes's spokesman. 'It's a problem looking for a cause.'
Also, adds Donoughue, most online gamblers are on sofas, with friends and family. 'There are lots of safeguards,' he says. 'You need a credit card so the underage problem and the financial limit are normally solved. (Although there are new cash-based ways of paying, such as Ukash.) Companies noticing problem patterns can email customers and lock their accounts.' And there is already a system of 'self-exclusion' from betting shops.
The trouble is, says Bartlett, that problem gambling is blown out of proportion. 'Problem gamblers are about 0.7% which isn't high. In Australia it's 1.4%. Our problem is booze, not gambling.'
And there are even positive arguments for gambling. 'Experiments have shown that non-addictive gamblers are better able to understand risk, probability and odds because they were gamblers,' says Donoughue. 'No one talks about that.'
And, lest we forget, the National Lottery is the country's biggest flutter, without which we wouldn't have all manner of things, from cycle paths to the Tate Modern.
The precedent for the disapproval, says Donoughue, derives from a Christian Socialist, 19th-century moral viewpoint. 'You still find it today. I had a conversation with a Labour party adviser who didn't like the "working classes" gambling. I mentioned the "nanny state" and she said: "I'm happy with that." But if you're poor why shouldn't you have entertainment? With lower stakes, and more things to bet on, there's a party going on that the killjoys don't understand.
Of course, some people are susceptible to compulsive betting. Gambling, says Donoughue, is about the brain 'dealing with randomness. We don't know what makes certain people susceptible but it's the same as drug addicts, alcoholics... ' It's latent in some people and online won't change that. 'The ubiquitous access bothers critics but only if they accept the "exposure model": that if you increase access you increase the problem.' He adds that there has been no discernible per capita increase in problem gambling between 2000 and 2010 when online came in.
But online does create problems, believes Harley Street addiction therapist Mark Dempster. 'There's no doubt about it,' he says. 'Look at the investment: the Ray Winstone adverts everywhere. There is so much investment in gambling.' The accessibility, the deals, the enticing free bets; all are creating 'a climate of acceptability' that will draw in new gamblers.
Like Dr San, Dempster says his problem gambler client-base is growing, and is 'disproportionately drawn from the banking world.
Partly this is because gambling can be more easily hidden than drugs and alcohol, and you find gamblers leading "Walter Mitty" lives, where even their families don't know they gamble. Online gambling enables this privacy and isolation.'
The 'reveal' usually occurs in a bank statement, particularly as, according to Dempster, gamblers are big users of payday loan companies. Nevertheless, online gambling does seem to be changing the working class, male, gambling demographic and luring the white-collar, educated, middle-income, young, tech-savvy and female gambler.
'It does seem to be more acceptable to be middle-class and have a punt,' says Donoughue, 'and we're seeing a growth in fair-weather gamblers.' One of the problems with betting shops is the 'threshold' - many people, particularly women, can't bring themselves to go inside them.
'I've observed a new kind of female gambler,' adds Donoughue, 'that play during the day when the kids are at school.' Online bingo is their taste and it is a sideways move from the 'ladette' drinking culture, reckons addiction specialist Liz Karter.
The Gambling Commission's latest omnibus survey showed that 55% of women had gambled in the previous month.
Dr Mark Griffin, a psychologist at the International Gaming Research Unit at Nottingham Trent University, has observed what he calls the 'feminisation of gambling. Remote gambling environments - internet and mobile phone gambling - are gender-neutral'.
Of more concern is that online gambling could prove to be an entry point for children and adolescents, and gambling surveys carried out for the National Lottery Commission have pointed to this vulnerability.
A 2011 study by Ipsos MORI, reported that 2% of 11 to 16 year-olds had played online lottery games.
Which is why, perhaps, we should heed Donoughue's call for gambling to be taught in schools. 'It's about education,' he says. 'Learning that you're going to lose.'
