The Max series won't look (or be) snakebit forever. Three years ago Volkswagen looked doomed because of the TDI emissions scandal, and there was talk of VW exiting the US market in a hail of criticism. Today that is mostly forgotten and VW sales have rebounded. The 787 had the longest, most tortured, error-filled gestation period of any Boeing commercial aircraft, its announcement and first revenue service were nearly a decade apart (2003-2011, with a fake "rollout ceremony" in 2007), and then the FAA grounded it in 2013 over the battery fires, but today all that is forgotten as well. Other airliners from the Comet to DC10 had long service lives following catastrophes related to design flaws.

So calm down.
