Well that can be done in the way they did with "Railtrack" in which it was a nationalization in all but name for a start, which we also did with 2 of our biggest banks, also you have to remember that we still have airports that are owned by government authorities in this country (remember most European states and even the USA have state owned airports).
Railtrack was a catastrophe and the banks crisis threw the whole economy into crisis, Airport strategy is most certainly not a national crisis where we need to throw what little money we have left at something. One thing about a lot of public airports in the US, I am thinking of Newark in particular, is they are quite poor by global standards. You really think the public sector can run airports better than the private sector?
The measures you are randomly throwing out there are emergency last ditch measures and not appropriate in this case. Read the thread(!)
