As to his service records from the war, as @Chickadee26 said, you need to apply to the National Archives. From Section 3.4 of that web page
"Records of RAF Officers who served after 1939 and who completed their service before 1963 have recently been transferred from the Ministry of Defence. These records are in the process of being catalogued and being made available on Discovery.
Records which have been catalogued can be found by searching within the series AIR 84 by surname and year of birth."
[...]
For records that cannot yet be found through our catalogue, or for records that are currently closed, you can request to access them by using our Request a military service record service.
Records of RAF officers who served after 1963 are still with the Ministry of Defence. Look on the GOV.UK website to find out how to obtain service records.

As to the factory, @Cotopaxi mentioned
"Just done some digging and it appears that there was a huge Royal Ordnance Factory at Aycliffe, near Gateshead"
The factory was never bombed, but it did have a number of explosions that led to deaths. Is it possible that it could be this?
For example, it was reported in the Newcastle Journal ( 23 Feb 1942 page 1 column 7):-
4 Women Killed In N.E. Explosion
Four women war workers, three of them married, lost their lives in an explosion at a Royal Ordnance factory in the North-East during night shift on Friday night.
It was a terrific explosion and all the victims were killed instantly. It is understood that they were the only operatives in the building at the time.
The building itself was completely shattered and other buildings in the vicinity were also damaged, many windows being broken.
The dead women were: Edna Thompson (30) single; Irene Irvin (24) married; Alice Dixon (22) married; and Phoebe Moreland (24) married.
The following official announcement was issued on Saturday:-
"The Ministry of Supply regrets to announce that there was an explosion at a Royal Ordnance factory in the North-East last night, as a result of which four women operatives were killed. It is not likely that production will be interfered with."
