Narrative:
14 September 2021: UAS DJI Mavic 2 Pro was written off (presumed destroyed) when crashed into the Firth of Clyde off the west coast of Scotland. The incident was the subject of an AAIB Record-only Investigation, published on 11 November 2021, and the following is the summary from the AAIB Report:

"While operating over water there was a power loss and the UAS dropped into the water."

Damage Sustained to UAS
Per the AAIB report "the UAS dropped into the water". There is no mention that the UAS was ever recovered from where it crashed and sank. Therefore it is presumed (although not confirmed) that the UAS was destroyed due to crashing into deep waters and sinking.

The Firth of Clyde is the estuary of the River Clyde, on the west coast of Scotland. The Firth of Clyde has some of the deepest coastal waters in the British Isles. The average depth is around 58 meters (190 feet), with the maximum depth reaching approximately 198 meters (650 feet).

The Firth is sheltered from the Atlantic Ocean by the Kintyre Peninsula. The Firth lies between West Dunbartonshire in the north, Argyll and Bute in the west and Inverclyde, North Ayrshire and South Ayrshire in the east. The Kilbrannan Sound is a large arm of the Firth, separating the Kintyre Peninsula from the Isle of Arran. The Kyles of Bute separates the Isle of Bute from the Cowal Peninsula. The Sound of Bute separates the islands of Bute and Arran.
