But is a cabin crew member going to assess a situation accurately, have the clear thinking required to grab the handset, call the cockpit, wait for an answer and clearly and calmly convey the message to the flight crew all within the time it takes to accelerate from 100 knots to V1?
Well why wouldn't they be able to?
You seem to be of the opinion that cabin crew are somehow not as capable or not as well trained as flightdeck in an emergency situation.
What is your evidence for this point of view?
