I don't have too much information. This is what I just got from a co-worker at the airport.

A Delta flight got struck by lightning while still on the ground and there was a fire in the cockpit. Passengers were inside and were evacuated. It is unknown if the aircraft was at the gate or on a taxiway. The flight number is unknown. Approximate time of incident is 7:30pm.

All flights currently grounded at MCO due to lightning.
