given secondary screenings. it took tsa two hours to report the incident to airport police. by then the passengers were already in the air. security experts say the lapse put everyone in the airport and on the ground in danger. >> a check point must be run properly fully staffed and if you are unable to do that it must be shut down. >> in a statement the tsa says in part, quote, a canine team was present at the check point at the time of the incident and we are confident this incident presents minimal risks to the aviation transportation system. now a chance to see a near perfect landing. the spacex rocket landed at kennedy space center. the young man rocket blasted off on sunday morning. it has landed five other times on sea

a winter without any real substantial cold air, that's for sure. especially in prolonged stretches. for now it's a cool but not cold early tuesday morning. 45 in washington. keep in mind -- you say oh, 45, that's chilly. our average is only 49 degrees so we'll be well above average again later on this afternoon. east to north easterly breezes today. sunshine and 68. today partly to mostly cloudy, close to upper 50s. 41 in prince george's county. hourly temperatures then, up and away we'll go, should be up close to 50 degrees by noontime and highs in your hometown today, 53 in gaithersburg. 56 in martinsburg. weather impacts for today, nothing to worry about. a little more cloud cover than we've seen. cooler but staying dry. no umbrellas needed for today. tomorrow, warm again. there may be an isolated shower chan

we take a look in our food fears series. >> gluten free diets, healthy or just hype? consider this. the number of americans who were gluten free or described themselves that way tripled between 2009 and 2014. but does being gluten free help in the long run and if so, who does it help? >> in terms of allergy it's only about a half a percent of the population that will have a wheat allergy but because of disease and gluten free diets being a fad it's a big topic. >> it's an auto immune disease which is characterized by an intolerance to gluten. >> i think that there's some legitimacy to some of it and i think other people just think probably less is better. >> gluten allergies are most commonly
