    Mission Summary for Dec 08, 2003

    Today's flight mission was a coordinated night time ER-2 and Citation flight to the SE. This flight was in conjunction with a satellite overpass and began with a takeoff from Bangor at 2154Z. The first sonde was dropped at 2229Z at a point (N43.6 degrees, W65.4 degrees) from approximately 30,000 ft. Subsequent sondes were released from 28,000 ft and were released at 60 to 90 n mi intervals down to (N37.9 degrees, W63.7 degrees), dropping a sonde at that point at 2340Z. This was the 6th sonde in the series. From this southernmost point, the track was reversed and sondes were released along the same track going northward, the last sonde being released at (N41.4 degrees, 65.9 degrees) at 0040Z. The total number of sondes released during the mission was 10. The aircraft then returned to Bangor and landed at 0145.
