I don't get it, even if the guy would have been saved because he was stuck in traffic that would still make for an amazing story (and for Frum Yidden, an amazing case of HP), why does it become less amazing (and more offensive) just because shabbos is involved? If you don't believe in HP or in the power of shabbos then focus on the main part of the story, someone narrowly escaped being on that ill fated flight.
