It would be illegal in Germany to shoot down a hijacked airliner and ordering the pilot to do so would be an illegitimate order the pilot would be forbidden from following. The most anyone could do would be the Minister of Defence of the Chancellor talking directly to the pilot and telling her that they would take the fall if her conscience allowed them to shoot down the plane. The pilot would still face a trial with uncertain results.

So, please stop with the alternative facts and the conspiracy stuff. Not every country works like the US of A, unbelievably.
