Important to remember that at SO1 level and below JFH of both cloths worked damn hard to provide the best embarked capability possible and it was embraced by all.
JFH didn't fail. JFH was failed- by an RAF leadership that wanted to eliminate FW FAA and by an RN leadership that sadly didn't 'get' maritime air power.
On the day of the announcement 1SL stood infront of all RN officers and said he didn't care who flew off the carriers, the important thing was that we were getting the carriers. That was the betrayal right then and there.
