Hi Richard,
Good Morning! Thank you very much. It worked :) .I struggled whole of
yesterday with this. Seems like I need to learn more basics about projection
first before I get in to this stuff.
Thanks again very much. Appreciate your help! Have a good day!
Sowmya.

It looks like your imagery is EPSG:2246 and your
SBET_Trajectory_Source is EPSG:4269
So keep it simple to start with:
1. Set your map to EPSG:2246
2. Set your map extents to the ones for the imagery 1532496.038000,
197080.590000 1543965.215000, 203467.824241
3. Set your SBET_Trajectory_Source to EPSG:4269
See if you get acceptable results.
