recorders being sent to USA
While the existence of corruption cant be denied....the DGCAs record on accident investigation has been pretty good actually(the reports of the last few years are available on line)
The Air Marshal who conducted the Patna 737 Court of Inq. in 2000 had put on line the entire FDR and CVR downloads pretty early on in the investigation, and his final findings were not challenged.
The Govt. and the DGCA is also quite open to accepting foreign(especially US)expertise as required.They have regularly done so in the past. And unlike the case of Egypt Air or Silk Air, the press in India is unlikely to allow a disenting view (if it were to arise)from the NTSB to go unnoticed without a vigourous(if sometimes ill informed!) public debate.
Already some good is coming from this sad event...the public is being educated by the media on the need to get the touchdown zone correct,sometimes at the expense of a "smooth touchdown"
The travelling public tends to rate the quality of the entire flight based solely on how smooth the landing was.
