Armed forces give answers only to government.unfortunately there is no way that the information is passed to common citizen.yes it hurts when you lost a jet but sometimes there are technical problems.inquiries are necessary and people are held accountable but common citizen have no knowledge.
Due to our laws and the procedures of insurance companies, we cannot hide or lie about aircraft losses.
But what we do hide is the reasons for losses in case the reason is critical for national security. For example, bird hit, pilot errors are revealed. But technical problems are rarely revealed, sometimes never.
The Mi-17 fratricide was human error due to failure to follow SOPs, so it was revealed. But if the reason was something far more serious, like failure of IFF or radar and so on, then it wouldn't have been revealed.
