The two times I heard loud bangs ,, one was a bird strike , Heli was put on Flat bed back to base .. EC130.

The other time was multiple compressor stalls , AS350 on final 300ft approx ,,,popped floats as I had two options at time , small helipad or water , maintained enough power to land Helipad. One of the floats partially inflated so water may not of ended well. 

It will be interesting to find out what caused Barrel Roll ( according to crew member ) if that happened in flight or on impact.
