Having traded through the flash crash in 2010, the problem was getting your stop filled. If you are in an active day trade with a reasonably close stop, it's ok. You might slip a bit but the carnage then happens after.
The problem is when you have limits set well below and they trigger, then slip, then your stop gets triggered moments later but you still haven't been filled for either. Usually, the brokers systems are all over the place at this point in terms of comms delays, database delays, etc. That's when it gets a bit gnarly.
A lot more controls were put in since then but still...
