Harry,
We all make mistakes, aviation has always been that way and always shall.
Accepting that fact shows no disrespect of anyone and we should always seek to learn from those sad times we lose one of our own.
I can assure you if it had ever happened to me I would hope there would have been a very honest and candid discussion of what happened.
If that were not done I would see it as opportunity lost that might just prevent someone else from falling into the same trap I did.
In this tragedy, some decisions were made that led to a very bad ending.
I would submit that flying in Cloud over downtown London at very low altitude while supposed to be VFR demands some cold hard consideration.
It may not be what you wish to see but the professional in you should accept the importance and propriety of that being done.
