Ted -

In the interest of providing some material for discussion, I ran
your estimate of 90 degrees of travel in 1 min (1.5 degrees /
sec) through my distance / speed spreadsheet for a range of
altitudes ranging from 1,300 - 21,000 feet. I used the
intermediate angle of 45 degrees elevation to calculate the
resulting speeds.

I also calculated the speed at 100 and 200 miles.

At 1300' = 33.33 mph
At 2600' = 66.66 mph
At 5280' = 133.32 mph
At 10,560' = 266.63 mph
At 15,840' = 399.95 mph
At 21,120' = 533.27 mph
At 100 mi =13,331.69 mph or 21,455.33 km/h
At 200 mi = 26,663.39 mph or 42,910.65 km/h

Most speeds at aircraft altitudes are not abnormal for aircraft
within those ranges. The rate at 100 mi is also not abnormal,
since the space shuttle travels at 28,160 km/h at between 100-600
mi altitudes.

The shuttle info is from

http://tommy.jsc.nasa.gov/~woodfill/SPACEED/SEHHTML/technology.html

The following are the equations I used (please feel free to
indicate if you think there are any errors):

Sight Distance = Ground Distance /cos(Elevation*(@PI/180))
Altitude = tan(Elevation*(@PI/180))*Ground Distance
Actual Size =(tan(Angular Size*(@PI/180))*Sight Distance)*5280
Estimated Speed = (tan(Angular Speed Per Second *(@PI/180))*
	Sight Distance)*3600
:Ground Distance In Feet = Ground Distance *5280
:Sight Distance In Feet = Sight Distance *5280
:Altitude In Feet = Altitude *5280
'Estimated Speed km/h' = Estimated Speed *1.6093472

Because the base and elevation side of the triangle are of the same
length, the altitude is the same as the ground distance.
