Tynecastle,
The Westland Sea King has an excellent auto hover: that's how it plies its trade as an all weather ASW platform! It followed on from the Wessex HAS1 and HAS3, both of which were also auto hover back in the mid 60's, but was a more refined and reliable piece of kit.
Not much new under the sun
Now, back OT: any of the workers in the Tsunami areas got any photos or updates?
