No. The jets were shot down as a result of the above mentioned action . PAF locked on military installations but didn't fire on them. They fired in the vicinity. Abhinandan and co flew into Pakistani space as a result.
General Yeagar's admiration for the PAF always gets the Indians really wound up. He's active on Twitter and the hatred the Indians have for this man is epic. He doesn't back down and responds to questions thrown his way.
DG ISPRdenied PAF role in its downfall but there have been a lot of reports that it wasn't a technical fault. It was most likely fratricide due to the panic in India after PAF strikes.
No it doesn't. You're confusing WC Usman Ali with WC Noman Ali. It says in the last paragraph that WC Noman Ali ended the show with a tribute in his F-16. But all that is irrelevant as a lot of F-16 pilots also fly JF-17s.
