From the BBC:
Their identities have not yet been released, but they were a couple in their 50s who lived in St Helens, Merseyside.
The man was a member of Cheshire Air Training School and was a frequent flyer from Liverpool airport with his wife.
'Wonderful company'
Roderick Geeson, from Cheshire Air Training School, said: "We're obviously very upset to hear of the death of our friends.
"They were very private people but wonderful company, he having been an active member of the flying club for over 10 years.
"They always came along to social functions, but he lived to fly. It was simply his passion in life and he would frequently come along to enjoy an afternoon's flying, with his wife accompanying him.
"They will both be sadly missed by all of us."
