I fly in and out of National all the time. My daughter lives 10 minutes away. On an earlier flight, some poor guy who didn't understand English got up to go to the restroom and two flight attendants and the sky marshall landed on him. Scared the poor guy to death. My last flight (yesterday) everybody sat still for that first half hour, interesting since the plane was going on to Guatemala with Miami (where I got off) as a first stop. The captain didn't make the announcement in Spanish, just English, but everyone seemed to have gotten the message.
