Runway is 10,000 feet and the airport is fairly sizable (35 gates) with lots of large jet flights. This is all probably nothing, but maybe not everything that happened on the plane is being reported.
I didn’t look up the field or the stats for a 777. Since this stuff happened to the same model plane at the same time that belonged to the same airline we gotta figure it connects to something American is doing maintenance wise or else a bit of sabotage. The oven cleaner angle is a real possibility. Maybe they went to some green eco chemical.
If my Dad was alive I would ask him about the field though it has been 50+ years since he was stationed there. They had F89 Scorpions then. He said they had to do FOD sweeps a lot since the wind blew so hard that lava rocks would actually blow across the runways. Especially bad for the Scorpions with the low mounted intakes.
