So both Rekha and myself are retired, later most of my career I have been working in safety-critical systems, designing and implementing air traffic control systems.

所以 Rekha 和我自己都退休了，在我职业生涯的大部分时间里，我一直在安全关键系统工作，设计和实施空中交通管制系统。

Of course, continuing to develop better strategies to handle these events from the top down will also go a long way, as well designing and implementing heartier tech.

当然，继续从上到下制定更好的策略来处理这些事件，以及设计和实施更强大的技术，也将大有裨益。
