India’s worst aviation disaster in recent years. Air India Flight 171 crashed within a minute after takeoff -- killing 260 people. In this episode of In Our Defence, journalist and aviation enthusiast Sandeep Unnithan joins host Dev Goswami to unpack the preliminary probe report that has sparked a polarised debate on the cause of the crash: How did the fuel switches end up in the off position?

The two break down:

Why air crash investigations aren’t about blame, but prevention

What the AI 171 preliminary report reveals (and what it doesn’t)

How the fuel switches were turned off -- accident, error, or something else?

The intense public reaction -- is it okay to even suggest “pilot error”?

Whether India’s aviation investigators can resist the pressure

Will this become another unsolved mystery like MH370?

While we await the final report into the tragedy, tune in for the first impressions on a preliminary report that raises more questions than it answers.
