The average pax lives for about 29,000 days. Therefore every day, out of each 30,000 people, one will die. That's about 75 747 loads, or about two hours' worth of departures out of London Heathrow. So it's not surprising that events happen on the day of flights. Each day, of Heathrow departures, for one or more pax the airline meal will be their last. That's just how it is.
