I think I must have a somewhat simplistic view compared with everyone else on this forum. I’ve been flying the 737 for sixteen years, first the 500, then 300 then 800 then the Max8. If something goes wrong a light comes on in front of us, we look up, see what’s happening, then either carry out the memory drills, or action the QRH, or both. If that’s safe with 178 passengers why isn’t it safe with 204. Or if it’s not safe with 204 why aren’t the 737 variants already flying being grounded ?
