Exactly what is the relationship between the ILS being OTS and the crew getting significantly slow on final?
It has about the same relationship as the price of tea in China. It doesn't matter whether the specific equipment at issue would have made any difference in this specific case. What matters is that the passengers are paying for equipment that works. If the equipment wasn't working then they didn't get what they paid for. No different than the fact that they are paying for pilots who don't crash their flights. Looks like the passengers didn't get that, either.
