Mani,
It is absolutely real.
I know The Editor says it can't happen but fly-ways, voltage drops and loss of controls are not supposed to happen but they do.
I will send an email this morning to DJI and the flight logs once I figure out how to download them. I checked my Ipad flight records and there is nothing there. It didn't register it as a flight even though this lasted a few minutes.
Maybe temperature was a factor. I had flown for 42 minutes (over 5 batteries, taking them down to about 60% so I could check them and then give them a full charge for a shoot today) with a temperature of about 38 - 40 deg C.
Cheers
