Hey Jeff, great new video. Like you, I also strongly think a northern route is still possible (even more since the wreck has not been found after extensive search).
For the northern theory to be possible, one would need to manipulate or spoof Inmarsat satellite data from the avionics bay, not the cockpit.
But there is one single detail that bothers me: the “ALT blip” theory.
The selector knob on the B777 transponder panel rotates through several positions before switching to STBY or OFF, one of which is ALT (altitude reporting) mode. Some radar data analysts and independent investigators have pointed out that MH370’s transponder briefly transmitted in “ALT” mode right before going completely silent. This blip would suggest the selector knob was being manually turned, and momentarily passed through the ALT position even if the intended final position was STBY or OFF.
This would be consistent with someone rotating the selector from ON to STBY or OFF and it is what you’d expect if a person was physically manipulating the selector in real time from the cockpit, not the avionics bay, and this instants after the famous “goodnight” message from the captain.
I’m really interested to hear your opinion on these aspects, since I believe are crucial to keep the northern route scenario open.
Question About the Timing and Integrity of MH370 Satellite Data
Hi Jeff,
Jeff,
I’ve been following your work on MH370 and find the podcast incredibly compelling—thank you for your persistence and insight.
There’s a question I’ve been turning over: is it possible the Inmarsat satellite data was altered after the fact—not during the flight, but at some later point, once its significance became clear?
I wonder if, at the time of the disappearance, even those who may have had access to or control over the data didn’t yet realize its potential importance. But once it became known that the satellite pings were central to the investigation, could the data have been retroactively manipulated?
Has that scenario been considered or ruled out?
Thanks again for keeping this mystery in the public eye.
Hi Steve, thanks for the question. There's definitely been some speculation to the effect that Inmarsat altered the data, but that doesn't seem plausible to me. If they wanted to cover something up, they could have just kept the whole thing quiet, and not told anyone outside the company that they had the data.

Hi Roberto, That's an interesting question, to be honest I haven't had a chance to look into this question, but I will.
