in the attack. investigators are now looking for possible links to other recent shootings at asian-run businesses. overseas tonight, and to a chilling new report. authorities believe a pilot deliberately steered a passenger jet into a mountain in china. this comes from the investigation into the china eastern passenger jet that plunged to earth earlier this year, killing 132. sources telling abc news the black boxes reveal that one of the pilots may have intentionally crashed that plane. abc's gio benitez covers aviation. >> reporter: tonight, in a story first reported by "the wall street journal," investigators now believe the 737 that slammed into a mountain in china last march was deliberately crashed. sources confirming to abc news that officials analyzing the flight data say it clearly points to someone in the cockpit intentionally pushing the plane into a fatal nose dive. all 132 people on board were killed. experts also cite evidence that the plane's landing gear was

never deployed. and the flaps were not engaged, both of which would have happened if the pilot or co-pilot was trying to land the plane. investigators believe the near vertical descent, as seen in this video, would've required intentional force. >> if you see a dive like this, that means somebody is forcing that airplane over. that's what indicates that this was not an accident. >> reporter: according to officials, investigators also looked into the personal life and background of one of the pilots, and believe he may have been struggling through certain issues that remain undisclosed right before the crash. the new details a chilling reminder of the germanwings horror in 2015. the co-pilot locking the other pilot out of the cockpit and bringing down the airbus a320 in the french alps, killing 150 people. that co-pilot had been previously treated for suicidal tendencies. >> the most chilling aspect of this, even just the initial speculation that it might have been a pilot who wanted to kill himself and take everybody else with him, is that it's happened

before. now we've got to be much more aggressive now in the international community and finding out how we can make sure it never ever happens again. >> reporter: and david, tonight, china has not publicly said what it believes caused this crash. and tonight, boeing does not believe that there is any mechanical problem with its 737 jets in service around the world. david? >> gio benitez tonight. gio, thank you. this evening, there is also a troubling new development in the baby formula supply crisis. we have learned this evening that two children were hospitalized in tennessee after they were fed alternatives to the specialized formula they need and that their parents could not find. here's abc's erielle reshef. >> reporter: tonight, a dire consequence of that nationwide shortage -- two children hospitalized in tennessee, after their parents were forced to find an alternative to their specialized formula made by abbott. >> they were dehydrated. i mean, they needed fluid, again, because these kids have -- it's not like you can give them rehydration fluids orally. they needed iv hydration. >> reporter: doctors say the

toddler and preschooler from two different families needed that special type of formula because of intestinal conditions. both kids had an adverse reaction to a non-abbott brand and blend. the hospital has run out of the formula they need, so they are treating one patient with fluids. the other patient was released after doctors adapted a formula designed for adults. >> we had to take a formula that's not really, you know, designed for what we're using it for and we've had to create some additions and bases in an adult formula. and alter it to where it will work for the patient. >> reporter: the abbott plant that makes specialized formulas may reopen in two weeks after an agreement with the fda, but it would take up to two more months to get their products onto shelves. and while the fda is moving to import brands of formula not currently sold in the u.s., that

could also take weeks. and doctors say that changing formula for most kids is okay, but as we have seen, for some kids with special health concerns, they may not be able to tolerate another formula. so doctors say that you should speak with your pediatrician or treating physicians to explore every option. david? >> yeah, this was really alarming to hear today. erielle, thank you. there's also news on covid tonight. the fda has now authorized booster shots of the pfizer vaccine for children 5 to 11. the cdc expected to issue guidance later this week. many doctors remain concerned because more than 70% of 5 to 11-year-olds haven't been fully vaccinated, and new child covid infections are at their highest point since february and hospital admissions up 57% in just the last month. and tonight, in new york city, the city is now at a high risk alert level because of what we're seeing here with increased pressure on the health care system. for now, masks indoors are recommended, but not required. tonight, the high stakes primary elections under way in five states. among them, the hotly contested pennsylvania senate race, including tv doctor, mehmet oz,

any regrets at all? did you go inside the capitol that day? >> no, she did not. and anything to the contrary is a lie. >> reporter: barnette presents herself as the "trumpiest" candidate. but the former president is backing one of her rivals. >> how you feeling today? >> doing very well. >> reporter: tv's doctor, mehmet oz. kathy barnette, your opponent, has gained momentum. are you confident that with trump's endorsement you will win tonight's primary? >> yes. i think kathy metaphorically had her moment in the sun. >> reporter: at his election eve rally, trump calling in, saying oz, not barnette can go all the way. >> he's going to have the easiest time of all in the election in november. >> reporter: and that was all one voter, pam dick, needed to hear. she was torn between oz and barnette. are you voting for dr. oz? >> yes. >> reporter: why? >> trump really feels he's the right person. and i trust trump. >> reporter: but a third republican candidate says trump picked the wrong candidate. david mccormick is married to the former president's one-time deputy national security adviser. >> it's extremely important that we put the best candidate

forward. that has credibility, experience, resilience. i think i'm the best candidate for that. >> reporter: and david, tonight, a major curveball in the democratic senate primary. john fetterman, who has been the front runner in that race, revealed just days before today's primary that he suffered a stroke. he's in the hospital recovering, tweeting out this photo of him casting an emergency absentee ballot. and then just hours before polls close, we learned that he had to undergo surgery to get a pacemaker. tonight, his rivals are wishing him well. david? >> big race. rachel scott tonight, thank you. to capitol hill, and the first congressional hearing in half a century on what the military calls unidentified aerial phenomena, what the rest of us call ufos. and hundreds of military encounters still unexplained tonight. here's terry moran. >> reporter: the military calls them unidentified aerial phenomena -- ufos, in other words. >> my gosh! >> reporter: they've mystified us for decades, but they also may be a real national security concern. today, a house intelligence subcommittee held the first congressional hearing on these close encounters in more than

half a century. >> we want to know what's out there as much as you want to know what's out there. >> reporter: pentagon officials now say there have been close to 400 military encounters with things in the sky they cannot currently explain. that's up from 144 reported last year. pentagon officials avoided speculation, but admitted how baffling this is. >> i can't point to something that definitively was not manmade, but i can point to a number of examples which remain unresolved. >> reporter: some incidents have been debunked, like this famous so-called pyramid video, leaked in 2021. >> whoa, it's getting close. >> look at that thing. >> reporter: officials couldn't explain it at the time, but now say it's drones in the sky distorted by a night vision lens to look like flying pyramids. the pentagon says it wants to destigmatize the whole issue of these ufos in order to encourage more pilots and other military personnel to report whatever it is they're seeing in the skies above america. david? >> really fascinating. terry moran in washington.
