I don't actually think there is anything connecting the two incidents, I was being flippant.

The details of this recent collision are a bit suprising though.

Subsequent news is that the helicopter didn't have a VIP it was a training flight, that it came from Fort Belvoir not Langley, that it had it's ADSB off but that MCAS doesn't depend on ADSB so they should have gotten collision alerts. The plane is split in half in the river. The chopper is upside down in the river.
