airlines? now you have a problem of cost of training. it is very expensive to train pilots in simulators. and so a small force airline may cut down the training cycle and as a former simulator instructor you don't give the pilots as much lee way which is normal on american carriers. >> sandra: spring breaks are coming up and people are worried about what they're hearing and seeing that happened here and checking to see if this is the particular model airplane they're flying. should there be fear about boarding one of these planes? >> absolutely not. look at the record. the airplane has been flying since may of 17. i can't troll through my sources where pilots talk off the record and find out that southwest or american has had incidents where the pilots have encountered this and the company is trying to hush it up.
