At 2040 UTC (22.4 hours after launch) we are at 1105 miles away from Newfoundland on course for Ireland.  The distance from Cape Spear, our launch point, to the designated point on the west coast of Ireland is 1888 miles.  This says we are more than 55% of the way there, 783 miles to go.  If we average 55 miles per hour, we have another 14.2 hours to go and the total flight time still computes to 36.6 hours, which puts the ETA at 1030 UTC (11:30 am IDT).
 
The airplane is still shaky on the engine and speed.  It is still porpoising plus and minus 50 feet, and the reported engine speed fluctuates from around 3500 to 4200 RPM.  We get data only once a minute and it probably depends on where the data point picks off the RPM, high numbers coming when the airplane is descending and low numbers when it goes back up the hill.
 
We have seen this in many flight tests, but it has seldom had such a broad swing.  And so we still suspect the engine is close to the lean limit.  We'll keep our fingers crossed during the night.
 
Joe Foster has programmed waypoints on each 10 degree change in longitude meridian.  We now have passed the 50 degree meridian, the 40 degree meridian, the 30 degree meridian, and are headed towards waypoint 6 on the 20 degree meridian.  There were two waypoints in the program dealing with a safe flight out of Cape Spear to avoid spectators on the parking lot and a second one to put the Futaba receiver to sleep. 
 
Joe has worked incredibly hard over the past four years to write the code for the TAM autopilot.  And it is a great satisfaction to him and to all of us to see it steering the airplane precisely on course.  If you have ever read Dava Soble's little book called Longitude dealing with the battles between a clockmaker John Harrison and the great Isaac Newton of laws of motion and how sailing vessels in the early 1700s often crashed into shore in a fog because they didn't know their longitude, you come to respect this modern technology that Joe has put to use as an awesome achievement. 
 
We still think there's a 50-50 chance of making it and we look forward to clucking cheerfully on Monday morning.
