Hello Fran,
I enjoyed your brother's book, but I have also made it through Sharkey's book a couple of times now and even subjected myself to 'RAF Harrier Ground Attack Falklands', which I found a little incoherent.
My personal highlight in Sharkey's book was when he sensed insubordination on 801 so took the offender up for some ACM and won....quite what that proved I have no idea. A little weird in my opinion. Your brother's best bit is when he tries to float out of his cabin to see his disciple....I mean, you wouldn't lie about that would you!
