The appeal has been going for about two months now, and without a major sponsor they're probably always going to need public donations.
I believe one reason for more cash needed is that some engineering work has been brought forward a year as they used up much more of the fatigue life than was expected last summer.
Anyway, no-one is forcing you to donate if you don't want to.
Very true,
I have been donating to the project for sometime but, to be honest, I'm suffering my own cash flow problems so am stopping now.
I wish the team well, having done a splendid engineering job. I'm less than impressed with the business planning, though (as my bank manager has said to me).
