Note: The latest elset has it all of 165 seconds late against the
predictions I posted here two days ago. The drag has increased much
less than expected; indeed the drag term in an elset issued earlier
today is the lowest for more than 3.5 days. This cannot be down to the
transition from free-molecule to slip flow - the rocket is probably
still too high for this to have a noticeable effect despite its length
of around 10m.
