Just don't answer to him mate, he thinks he is being clever by using Altay as an example non stop, i would explain why he is wrong but i will not entertain a troll.Altay is a political failure. Kaan and TF-35000 is an engineering challenge. Both TAI and TEI has world class expertise. TAI was one of the most important suppliers of the F-35 project, TEI supplying advanced engine parts for other engines for decades now. If you fly regularly, you probably flew with an TEI produced engine part. Neither of them starts from 0.
I wish a moderator deletes all this nonsensical off-topic argument.
He is under propulsion systems and compares jet engine development to Altay tank failure which was due to engine embargo from Germany, that's all i gotta say, he does it on purpose.
