It is my view that you should avoid such a venture. You have neither the experience or I suspect the finances or the set-up to undertake it. You would NEED all three in abundance.
And in needing all three you would be required to pay substantial deposits to Manston, aircraft owners and the knowledge to deal with police, fire and other services.
Get some experience by working with an established organisation - 3 years would do it.
Sorry, but you did ask.
