The Project Blue Horizon 5 high-altitude transatlantic balloon flight originally scheduled for Friday, April 22, has been postponed to April 27 - 29.

The Project Blue Horizon team is attempting to break current Amateur Radio high-altitude balloon records for distance (3361.81 miles) and duration (49 hours, 45 minutes). The payload will be carried beneath a 54,000 cubic foot capacity helium-filled balloon cruising between 85,000 and 100,000 feet.

During the flight amateurs worldwide are encouraged to monitor the N2XE CW telemetry beacons at 7.1023 and 10.1466 MHz. The balloon is also equipped with an APRS beacon at 144.39 MHz using the call sign KC2ZJH. Amateurs can send reports via e-mail to [email protected]. More information about the program is at the Project Blue Horizon website. Launch and flight updates will also be available on Twitter.
