Hail does not paint at all on radar unless it is wet hail. Hail can be thrown a considerable distance from a storm. In some cases 20 miles downwind.The aircraft was not totaled. Delta is parking the 747 fleet. 3 airframes had just been parked and 5 more will be parked in the fall. No point at all in fixing the airframe. Just grab one of the 3 just parked and put it back in service. It will be parked again in OCT probably forever. The 747's Delta has are very high time. Their only value is in the engines.
