Of course you and Henry are correct. I should have thought this one through more carefully. I suppose one advantage to the Shuttle is it allows you to launch things that are WAAAY too expensive to replace and must be repaired on orbit. Whether it was really necessary for the Hubble to be built this way is probably another matter. -- Sean R. Lynch <http://sean.lynch.tv/>
