Chinese surveillance balloon didn't follow 'normal protocols' before launch
Astrophysicist Dr Brad Tucker says it is clear China did not follow all the 'normal protocols' usually conducted before the launch of a surveillance balloon. 'When you launch these things, you have to have certain tracking beacons operating on certain frequencies - you have to issue what is called NOTAMS, Notice to Airmen, because you are going through civilian airspace,' he told Sky News host Chris Kenny. 'This balloon did not do a lot of that, so as much as they say it blew off course, they didn't even do the beginning things that would make it clear this is a civilian scientific payload.'
