There were rain storms moving through the general Washington, DC area, and I’m including where this accident happened during the general time of the accident. Thus I would not be surprised if bad weather is a factor in the crash.
Microburst season.... no warning and no detection after the fat.
It only drizzled all day and has been sunny since around 10 AM
An F16 crashed last week in Maryland near Andrews.
The original reports said they were in a flight of three and started falling behind, then the ship started rotating and crashed. Too early to speculate on cause. The Blackhawk does have a small window for controllability without the tail rotor.
