How important is accuracy to detail when safety could be jeopardized?

There was considerable deliberation on whether the wings should be left flat plywood (like PorchRocket), or crafted into airfoils as found on Space Shuttles of full size. The additional time and labor was not in question, but rather the lift generated by an authentic lifting body design application. The decision was made to accept the lift but over-engineer the attachment mechanism to prevent unintended separation of Shuttle from her external tank.

Calculations of proportionate wind speeds indicate 58.3 mph = Mach l.
