I think the airport will survive BUT certainly not as a vibrant centre for passenger flights, at least for the next few years. Survival will depend upon diversification into a range of aviation related businesses (many of which SEN once had and some of those until quite recently). An unlikely series of events after 2019 showed that putting all their eggs into one basket at the expense of less high profile baskets was a disastrous mistake by management. If it wasn't for bad luck SEN would have no luck at all, but blinkered management decisions left it vulnerable - as was pointed out by several of us years ago, not least Expressflight and LTNman.
