There are no technical issues, and the weather is estimated to be 90% probability of acceptable at launch time.

There is this, though, which I think is something that we will need to deal with to make spaceflight routine:

The Air Force will be clearing a Launch Hazard Area off the coast of Cape Canaveral, and mariners are being asked to keep out of the danger zone between 7:30 p.m. and 12:30 a.m. Friday.

Violators can be fined up to $250,000 and jailed for up to six years. A map of the danger zone is: launchhazardarea.doc.

OK. We've warned them. The probability of anyone in the box being harmed by the launch is infinitesimally small (it's the joint probability of a launch mishap and such mishap actually affecting a boater).

Is this really a justification to hold up a launch that costs hundreds of millions of dollars, and the delay of which could cost many thousands or millions of dollars, or in the case of a military launch, not having a military asset on station during war?

This is a stupid policy. It should be changed. Chase people out of the box, and fine (and even imprison) them if they are there, but don't hold up the launch over it. Please?

[Update a few minutes later]

OK, on reconsideration, I now realize the reason for the policy. It's not to protect the boaters. It's to protect the launchers from a boat-fired missile.

But still, we manage to do thousands of airline flights per day. Why can't we do it for space launch? It seems to me like a great application for an anti-missile system, installed at the launch site.
