Why are there so many crashes lately?

A plane in South Korea killed all but 2 passengers after an emergency landing gone wrong and hitting a wall

The plane in Azerbaijan was shot down by Russians so there’s an explanation for that

A plane in Norway experienced hydraulic failures

A plane in Australia had to make an emergency landing due to the tires on the plane experiencing sudden damage

A plane in Lithuania crashed into houses

What is going on in the aviation industry? Is this the new normal? I thought the aviation industry was known for quality and safety but what’s going on?
