Hi!
The helicopter, like any army helicopter, more or less followed the coastline. So much so as not to get lost, and so as not to fly over the sea. There is no radar track, but we know the flight plan, the time of take-off and the exact time it was hit by HMS Coventry's Sea Dart.
We also know the position of HMS Coventry, the distance from the ship to the target and the time of flight of the missile.
With these data, the search location is north of Lively. More or less.
Best!
