BubblesUK, thanks for the extra gen and as a long term member of the VTSC/Forum my panic level was no different to the rest, as for my last comment I quote this taken directly from the press release as this is why I wrote the response to Hurn:
Be warned: while it looks like the target will be met, if the pledges are not realised, then there will be no more lifelines - Vulcan XH558 will become a static museum-piece because the funds required to salvage the situation from that point would eclipse those required by the pledge campaign.
but then add this (applies to Judd Power as well):
However, we - Aerobytes - would not have invested this money unless we had a very realistic expectation of the pledge target being met (subject to continuing publicity) and the pledges being converted to cash.
