I would suggest that the first thing you should do (if possible) is to obtain a copy of his service record which will provide you with information on his training and his postings.
Details on how you do this, along with the rules and regulations, can be found at:
www.gov.uk/requests-for-personal-data-and-service-records. It is worth noting that more details are made available if you apply as next of kin.
You will have to pay to obtain the record and my understanding is that it is taking months (rather than weeks) for them to be sent out by the record office, so be prepared for a bit of a wait.
Once you have this record, you can establish where he was posted and obtain the Operations Record Books for the squadron(s) he was involved with from the National Archives.; this should provide details of his sorties and crew.
In the meantime if you can provide any dates, or additional snippets, it may help other forum members find information in their own archives.
I hope this is useful; good luck with your research.
