UH-60 Black Hawk sighting, east of Leeds Sunday 11/07/21.

[06L]

Could anyone help with a sighting of what appeared to be a UH-60 flying very low to the east of Leeds yesterday evening (Sunday) at around 6pm?

It was heard ‘growling’ and seen briefly by a relative of mine and was heading south.
It was not transmitting its mode S (was not showing on my relatives SBS), and as expected, was not showing on ADSBexchange either.

Did anyone else catch sight of this, or have I overlooked it (or something similar) being posted elsewhere on the forum?

Thanks in advance.
