The future of aviation in a free Scotland would be brilliant. The reduction in Navigation Charges would stimulate overflying traffic that wishes to avoid former UK fees, and as Scotland would take about half of the current UK "sky", the overflight income would be significant; especially without the need to financially support the [well lets just call them "other things"].
Scotland would have the potential to become an aviation growth area by expanding hub-and-spoke operations throughout the remaining UK and Europe. Just imagine that [like the Irish] the draconian anti-aviation taxes on air travel are reduced to such a level that the lowland three big airports become massive transit hubs.....jobs/jobs/jobs!!! Forget Heathrow and Gatwick in a free Scotland future.....they're already pricing themselves out of the picture, not helped by shortage of slots and horrific government taxes.
Local communities would be huge beneficiaries; a free Scotland might consider the relaxation of regulations concerning single engine transport. Cheaper overheads would stimulate air access to a greater number of small community airfields, with potential for economic stimulation.
What about a Scottish registration in line with the Channel Islands/Isle of Man.....very successful I believe.
On a personal note I can't believe that freedom can come as easily as a simple vote in a land where the the ground is soaked with the blood of so many that that gave their lives for the same end.
