This is so sad news. ""Opa" David Marshal was such a helpfull person. I will miss him deeply. He will not be forgotten. My deepest condolences to his family. Schlaf gut, "Opa"... Dedl

Whenever I had a flightsim issue and came to the forums to search for answers, my search would always end up on a posting by Opa. While I may have exchanged some PM's with him, he helped me out in SO many more ways than he ever knew. I will miss him greatly. So long Dave...blue skies, thank you for making my FS experience what it is today and thank you for being a kind gentlemen. My thoughts are with his family.

what horrible horrible news such a kind hearted and respectful man taken away I'm at lost with words my condolences and prayers go out to his family and friends. we will miss you very much David.

Rest in Peace, old friend. David was not only my friend, but a genuine friend of everyone who came within his penumbra of gentleness and humility. My sincere condolences to his family on their loss. I will be offering a Novena of Masses in David's memory.

Such a shock this is! One of the great one's is gone and I'm lost for more words...peace to David and his family. I must grieve now... Greg G

I don't know any other flight simmers personally, but I have often wished that Opa lived down the street from me.To be able to share his infectious enthusiasm for the hobby and to benefit on a personal level from his knowledgable and methodical approach to problems. I will particularly remember him for 'Tips and Tricks.', his Runway 24 tutorials , and as others have said, a non-judgemental approach to posters on various forums including myself. More important than anything else, he was quite obviously a nice guy.My thoughts are with his family tonight. RIP and thank you David.

We will miss him, and to honor him I suggest we all try to be an 'Opa' David, and help each other more out here.

well said Johan

It's kind of hard to accept that we won't be seeing his replies to posts any more on this and other FS forums. It's truly like a family loss for someone in this community.

Terrible news. A great loss. Sincere condolences to his family. RIP - you will never be forgotten here.

Deepest sympathy to the relatives. Have a nice trip Mr. Marshal. Regards,Vital VanbeginneBelgium

So very sad o hear that OPA has passed on. I always read his postings as they helped me get much more out of my hobby. You will be missed by all OPA. On the bright side OPA you finally have your wings my friend! Tinhead59

My deepest condolences to his family. I always remember that his tips and additions on Avsim all the way to my first days within the flight sim community twelve years ago. To me, his name was subconsciously synonymous with flight simulation. I am shocked and saddened by the significant loss to the flight sim community. I hope that many people in this community will fondly remember him as I will. Descanse en paz. Esteban
