I have friends at Lockheed who had to work all night long on this S-76 copter blowback, and it is really unfair. It’s an exceptional, safe craft, and it should NOT have been flown yesterday when police and other copters were kept grounded.
This particular S-76 was IFR rated (and pilot) which most copters are not...
Probably why the Police copters weren’t running...
Ground fog is not an issue for aircraft unless take-off or landing.....
However, in the case os a malfunction and having to emergency land in a fog-bound area, all bets are off...
