Transcript for Pressure mounts on FAA to ground Boeing 737 Max 8

Here in the U.S. Pressure is mounting on Boeing and the FAA to take action. A number of airlines grounding the Boeing 737 max 8 around the world is growing as the first Canadian airline joins the list and take a look, those are the Boeing 737 max 8s flying in the air just last week. And then look at this. This is the number overnight. So let's go to ABC's David Kerley at Reagan national airport with more. David, good morning. Reporter: Good morning, Paula. The more than 77 maxes are in service and one took off from right behind me earlier this morning. Despite all that worldwide action the FAA says they can fly for now. Countries and airlines around the world this morning are grounding or banning the 737 max 8. But here in the U.S., the FAA is doubling down against such a move. We've learned there have been reports of concerns. Two U.S. Max pilots telling authorities in November that the nose of their plane suddenly dipped after engaging the autopilot. Another pilot also anonymously complaining about a lack of training for the new aircraft. The FAA says there are no verified incidents in the U.S. Similar to the first crash and it has no basis to order grounding of the newest version of the 737. It has been involved now in two crashes in less than five months. The president jumping into the debate now tweeting that modern jetliners are too complex to fly. That led to a phone call with the CEO of Boeing who told the president his company's planes are safe. "The New York Times" reporting the head of Boeing asked the president not to ground his fleet. Around the country passengers are asking am I flying on a 737 max? Do I want to? No. That's scary. I think getting to and from the airport is more dangerous than getting on the aircraft. I dflg would do a different plane. Reporter: In both the ethiopian crash and the one in Indonesia last October flight crew as parentally had trouble right after takeoff controlling the aircraft. But there is no indication suggesting those two crashes are related. We're still learning more about the eight American victim, among them Dr. Manish at east Tennessee university on her way to Kenya to visit family. Her sister had just given birth to triplets and was excited to do this. Reporter: And Matt from southern California. He was excited to attend the U.N. Environment assembly for the first time. Now, the FAA says its decision not to ground is based on evidence, that's why the data from those black boxes is so important and so timely as well. Cecilia. It's all about the black boxes right now. Thank you. Let's bring in colonel Steve ganyard, a former marine fighter pilot and aviation expert, good morning to you, Steve. So we just heard David Kerley there say, you know, the fight over this black box has lasted days and know now they could be sent elsewhere likely to Europe somewhere overseas. What has this delay done to the investigation. It's inkukesable. Every day they delay is another day we don't find out what happened to had airplane. The investigation should be going on in par Lemm. They have the black boxes and need to do the analysis of the data and do the crash site. Look at this black box which is really Orange so they can find it. It is a big hard drive and talk about the mishaps, find the black box. That's because this will almost always answer why an airplane went down so every day the ethiopians delay it they're putting the general public at risk. China, Europe, Australia, South Korea, countries all over the world saying we're not going to fly this plane right now. The FAA is holdinging firm and you think that's the right decision. I do because there's no scientific evidence at this point that says there is a problem with this airplane and so until they find a problem we need to continue to fly this airplane. George, when the lion air airplane crashed that was brought down by maintenance malpractice and pilot incompetence. People are understandably nervous but right now this is a perfectly safe air plain until we find out otherwise. Thanks. Now to that massive storm
