Delta 747 adventures
Not trying to pick on these guys/gals, but seriously? Fly through or near that bad of weather in the first one then wait for 30 minutes with an active fire indication while dumping fuel.
Accident: Delta B744 over China on Jun 17th 2015, hail strike
A Delta Airlines Boeing 747-400, registration N664US performing flight DL-159 (dep Jun 16th) from Detroit,MI (USA) to Seoul (South Korea), was enroute over China when the aircraft encountered hail causing substantial damage to the aircraft's radome (hail penetrating the radome causing a large hole) as well as leading edges of wings and tail plane. The aircraft continued to destination for a safe landing.
The aircraft is still on the ground in Seoul 13 days after landing.
A passenger reported while over China the aircraft encountered severe turbulence and hail. The crew announced they had requested to deviate around weather but did not receive clearance to do so.
Incident: Delta B744 near Shannon on Jul 3rd 2015, cargo smoke indication
A Delta Airlines Boeing 747-400, registration N671US performing flight DL-73 from Amsterdam (Netherlands) to Atlanta,GA (USA) with 392 people on board, was enroute at FL320 about 100nm northnortheast of Shannon (Ireland) when the crew declared emergency reporting an aft cargo smoke indication, dumped fuel, activated the cargo fire suppression system and diverted to Shannon. The crew indicated they still had an active cargo fire indication but were dumping fuel and needed delay vectors. Air Traffic Control in the meantime, while advising emergency services, were unsure whether the flight was a cargo flight or passenger flight, Shannon Center subsequently requested the number of souls on board, thereafter Shannon Tower advised emergency services of a passenger flight with 392 people on board. In contact with Shannon Approach the crew advised they were planning to vacate the runway after landing and stop just off the runway. ATC became concerned with a survey aircraft at 1500 feet MSL as the Boeing 747-400 still dumping fuel was inbound at 4000 feet near the survey aircraft. The aircraft landed safely on Shannon's runway 06 (winds from 140 degrees at 19 knots) about 30 minutes later, vacated the runway and stopped past the hold short line, shut the engines down and instructed emergency services to not yet open the cargo doors. A tow truck was dispatched to the aircraft and towed the aircraft to the apron about 25 minutes after landing. Emergency services did not detect any trace of fire, heat or smoke.

Had there actually been a fire (and not just a perpetual indication of one) there would have been secondary clues that the cabin crew would have easily been able to detect; heat, smoke, something. If there had been a fire that was unextinguishable even when flooded with halon, both of those clues would have been present in abundance.
Had the airplane actually been on fire I'm certain the crew would have landed, but barring any actual evidence of a fire, they more than likely deduced (correctly) that it was an erroneous warning, and elected to continue dumping fuel in order to prevent another accident associated with a grossly overweight landing, but fully prepared to put it on the ground should actual smoke or heat have been detected by the cabin crew.
