Incident at Along Track Romeo over NT (Conflict - potential)

Summary

2003-07-18: A scientific balloon launched from Svalbard, Norway on a circumpolar high altitude mission descended into Canadian controlled airspace. The balloon has been declared as 'rogue' by the Andøya Rocket Range operators who launched it. It is currently drifting along ACA Romeo Southwestbound at 15 knots. The latest position report has it descending below controlled airspace in the vicinity of 82N 146W in Alaskan airspace. The balloon may remain aloft for weeks. Position information is being relayed to NAV CANADA as received by balloon telemetry. Battery life of the telemetry unit is estimated at 20+ days, we are now at day 8. The balloon has been relatively stable between 31,000 and 33,000 feet but may affect FL 290-360. It will penetrate Alaskan airspace some time on July 18, but it is expected to pick up an easterly wind and possibly drift back into Canada in areas that would have a greater operational impact. A rocket range official (from the launch site) has stated: 'As the situation is, once the balloon descended below the 30 km range the data was of no use to us. I would support any method for terminating the balloon where it is before it causes any issues.'
