As JetBlue flight 321 from Boston to Palm Beach International Airport came to a stop at the arrivals gate last April, John Allen Fletcher suffered a massive stroke.
When Fletcher, an 89-year-old Vietnam veteran who spent more than two decades in the U.S. Air Force before embarking on a second career building jet fighter engines for Pratt and Whitney, stood up to get his carry-on bag, he immediately collapsed back into his seat, according to a wrongful death lawsuit his daughter filed in January.
