“The controller responds "I can’t have this conversation with you, you either divert to Oakland or you can continue to hold, it’s up to you"”
Lufthansa LH458 reached San Francisco in clear weather and diverted anyway, because Lufthansa bans its pilots from visual approaches at night. Instrument approaches need wider spacing, so SFO parked the A350 in a hold until fuel ran short. It landed in Oakland at 9:43PM after 12 hours 13 minutes and finally reached SFO at 11:55PM. A safety rule nobody told the controllers about cost a full plane five hours.
