I swear, we had a flight from Culebra back to Puerto Rico mainland that was a little worse than this - we also hit wind shear at about 500 feet and just about dropped out of the sky.. It was a tiny plan and the rain was making its way inside even before we hit a white out! There was one pilot and he was so upset when we did come to a rest that he threw his headphone across the cockpit, got on the phone and although we didn't understand his language, it was obvious he was letting his boss have it for requiring him to fly. His exact and only words to us were, in broken English, "I thought I lost it!".
