That is reassuring, but I wonder how this principle reconciles with a security situation that has become so bad that it warrants armed personnel to be present on a flight?
Are you saying that since just about any flight
can be considered a terrorist target, that we cancel all of them?
The armed marshalls, imho, are no different (and potentially less dangerous) than the oxygen generators installed on aircraft. Since O2 generators can possibly cause fires, shoud we cancel any flight with them installed, on the remote chance of that happening?
There is always the remote possibility that an engine will catch fire in flight. Does accepting this possibility somehow make the flight less safe, or do we accept the remote risk and train to deal with it?
Marshalls are another backup emergency system, like pax o2, redundant hydraulic/electrical/fuel/air systems etc.
