720B, get the bus then. You have the choice, if you don't like it no-one forces you to fly. Instead of misusing the loss of those aircraft, perhaps you might want to look at the events that actually took place and how security, screening and processes have changed since then. I would even suggest that if anyone made a run at the flight deck, the other 100-odd passengers would get in the way very quickly - just look at the event in the USA yesterday.
