Saddening news from Gulfstream;

One can imagine how hard they were pushing the plane in
pre-certification testing, and while this tragic accident should not
really undermine faith in the new design, it could delay certification
which would probably lead to cancellations. Hard enough to market a $65M
private airplane in today's economy without something like this.

The human cost is high as well. The chief test pilot was 65, and was
probably looking forward to retirement.
