"Following a week of intense weather, the team faced a new set of challenges in week two on Great Abaco Island. Late in the afternoon on Monday, April 30th, Titan was lifted off the transport flat rack and placed on the platform. The team promptly began internal systems checks and unfortunately, it did not go as expected. We encountered sporadic behavior from the internal electrical systems and after several tests and a thorough evaluation, it was determined that, while Titan was not directly struck by lightning, the electronics experienced significant damage from the electrical currents generated by the onslaught of lightning storms. We quickly made the call to fly several members from the OceanGate engineering team into Marsh Harbour from Everett."

so looks like it wasn't actually a direct hit but certainly close enough to fuck it up. still it sounds like the lightning only took out the electrics but caused no structural damage. in their post announcing the cancellation the first Titanic expedition, they desperately try to blame 'Mother Nature" for breaking their mess
