You are quite correct that Andreas no longer excepts visitors for the very reasons quoted above. The runway is indeed very rough.
I see Andreas as an example of the Manx governments economic shortsightedness the curent owners can't afford to resurface the airfield but would very much like to keep it running. The airfield did bring a lot of revenue to the Island but this revenue goes into the local taxis, hotels & resteraunts NOT the airfield owners. In short the whole Island economy would benifit from Andraes running as an airfield because it will attract the type of flyers who would not go to Ronaldsway.
The cost of resurfacing a strip of both the runways 20 m wide by 800 m long and adding a bit of hard standing would not break the Manx Govenments bank and would be an investment that would last thirty years, the north of the island would see a modest but sustained increase in business over this period.
Unfortunaly there are very few politicians with the farsightedness to take on such a project, these days it is all short term thinking and Proffit rather than statesman like investment in the future to benifit the future generations.
In short the Manx should not let this airfield go the same way as the wonderful railway system they had and are now wishing they had not wrecked.
