I can only say what made them a great team back in the 70's. I doubt they have changed since.
1. They don't choose prima donnas for the job.
2. They have personalities that enable them to mix with all types and particularly the public.
3. They ensure that their groundcrew and support crew are all part of any social events that they get invited to.
In all...a good bunch. My only regret is that I didn't pester them for a ride when I was a Herc captain!
Perhaps the greatest compliment is that I now spend time with both Battle of Britain and Bomber Command veterans...and from what I've seen of the Reds. they would fit in famously.
