All these excuses, and for both drivers!
No incident =no drug or alcohol test?
What about opinion of the UAL 1 driver, he did not appear too impressed?
What about the PAL drivers?
OK, so you're half an hour from landing, you realise you're dog-tired, you're not in a position to stop.
As professionals, you are both so dog tired after a 6 hour flight that you are incoherant to land the aircraft? What part of being a professional is that?
Forget about the 400 pax, right? They all have the expectation that the people driving will get them there and are professionals. According to all the posts with excuses, the drivers were tired because it is such a lousey profession, great excuse. Its okay, just like the one who drove it into the mountain on purpose, he was real tired too.
