Your story is a perfect example of why disconnecting feedlines is
not real good protection if proper attention was not paid to the
overall grounding scheme of the station. The scenario you
describe happened because single-point grounding was not in
place. If you do not tie house electrical service and telco
grounds to the tower ground and main station ground point then
you will have many avenues that lead to trouble.

Kelly:
Not as contrary as it may seem. A friend of mine, Herb, WJ5D,
now a SK,
back in the early 90s had all of his antenna coax, rotor cable,
etc.
disconnected, when his 60 ft. tower took a lightning hit. The
strike
traveled down the tower, into the ground through the 3, 8 ft
ground rods
(1 to each tower leg), traveled under his house and back up into
his
station (on the opposite end of the house from the tower) through
the
station ground. Fried all his equipment beyond economical
repair.
Nothing would have been damaged has he disconnected the station
ground.
I've had a couple friends that now completely disconnect
everything and
put their HF rigs, etc. in the middle of the room, away from any
grounds, coaxes, etc.
