Agreed. With caveats :D They do know the expected expected min, max speeds of the riders, and the most likely time. I assume that when they file their flight authorisations long in advance that they are declaring the time slots that they will need over airspace, and probably do have scripts for those min/max rider speeds so that they know +/- some margin of error the earliest and latest the helicopters should be anywhere. Although I'm personally more interested in the plane circling above them for 4 hours :) It makes sense to have it, and has anyone a link to one of it's daily routes?
