Police are urging residents not to be alarmed if they see a low flying Blackhawk helicopter off Jennings Beach this morning.

Fairfield police say it is part of an air flight testing.

During the tests, the Blackhawk will be hovering at a relatively low altitude over the water, testing a Bambi Bucket.

The testing involves multiple filling and emptying cycles throughout the day.

It is taking place today and tomorrow from 10 a.m. until 2 p.m. depending on the temperature.
