I will make the point one more time.
People make airports not runways and landing aids.
Before DSA opened the hype was so bad, some idiots were writing to publications about how relieved they were about not having to drive to Heathrow anymore for their long haul flights to the Far East,South Africa,the USA and South America. They never questioned why EMA or Stansted or Manchester for that matter could also not attract this business.
They believed that the DSA runway was longer than any other in the UK and this was all the airlines had dreamed about.
It is like designing a product then looking for customers to buy it.
Horse water and drink spring to mind.
DSA may make it in the distant future but I would not put money on it.
There will be more point to point flights from established airports that can already accomodate smaller aircraft for meduim to long haul flights with no market requirement for the Goliathans of the air.The 787 and A350 will create new markets.At the end of the day, the DSA runway is only average and the same length as EMA and shorter than Stansted.
