Monday 09-09-24 - flying Chinooks help please

[D1scafellpike]

Could anyone identify the Chinook that did the "role demo" that commenced just before 13:00 (it was described as "role demo" over the radio though it was more like the displays of a few years ago. The Chinook also appears to have had a new front port side window fitted) and the Chinook/Chinooks that carried the underslung loads ( 2 barrels circa 14:25 and 2 + 3 barrels circa 14:55) please ?

I was in a layby nearby for a large part of the day and there was quite a bit of activity, although as usual, not all tracked on adsb.

Thanks in advance.
