In the last several days, the Friends of Jim group has reviewed all the data with Coast Guard officials. The fact is that we have no evidence as to what has happened to Tenacious or to Jim Gray. Neither we nor the Coast Guard can come up with a surface search plan that is likely to find either Tenacious or Jim, given everything that has been done already.Accordingly, the Friends of Jim group is suspending its active effort to find Tenacious that has been centered here at the blog. For both the Coast Guard and the Friends of Jim, “suspension” means that the active search has been discontinued due to exhausting all present leads and the lack of new information. Of course, should we or the Coast Guard receive any new information, we will investigate it.
Jim Gray is a pioneer in database research, and contributed greatly to the concept of transactions with roll-back and roll-forward, all very commonplace nowadays. Late january I posted about his test of Sun's thumper, apparently on the same day he went out sailing solo out of San Fransico Bay into the Pacific. He's been lost since. All efforts (and they've involved some very high-tech methods) so far have not resulted in any trace of Jim or his vessel, the Tenacious.
