I am totally baffled by What kind of radar systems do Bangladesh and Nepal have. I keep hearing about the Bay of Bengal. Is it possible the airplane flew relatively low altitude over Bangladesh and then the short stretch of India before going up in altitude over Nepal and then western China (Xinjiang)?
Possibly pro-Uighur perpetrators?!?
I've been thinking about this, so I spent a little time searching the interweb and I found this ICAO report from Jan 2013 that has an interesting map.
Here is the map from the report:
I added the red star and the red line. I'm thinking that the red star could be where the Malaysian ATC had its last radar contact, and I just made the red line up as what looked like the path to the north search area that would go through the least amount of primary radar. I'm no radar expert, but I did read a report that on the same ICAO web site that says that the perfect circles that are used in these kinds of maps are very optimistic, and that terrain and other factors can effect range. So perhaps it is plausible that an experienced pilot found a way through undetected.
After all, this is part of the strategy that any military would use to defeat radar in a conflict. Since the transponder communications were off, I don't think the blue circles would be a threat (correct?). Also, that path traverses the Himalayas, and I'd not be surprised if military radars in the region are affected by them as much as civilian radars might be...
I'm hoping to add this data to my live map, but it will take some time, this data seems hard to come by. if anyone has a list, csv, or kml of ATC surveillance locations, lat/long or just the airport name, I'd be happy to plot it on the map.
Anyway, I'm not an expert, but it is in interesting thought to consider.
Hope this works out for these people on the plane,
