 Well, perhaps the flaw in the ointment is the assumption that you can get
 210kts of TAS at let's say 15000 or 17000'..... :(

 So, theoretically, if you could find 20kt tailwinds, with 210kts TAS, you'd
 have a ground speed of 230kts.  Now if you could come up with the right
 combination of power/fuel burn and speed (TAS + strong tailwinds), you
 should be able to beat this record.
