Thank you all who have put in their input, relevant/pertinent, farcical/fanciful or any which way.
The lack of facts made even the conspiracy theories useful : after all up to the time mh370's black box is found, we are only scenario painting.
For the the few professionals who were worried that some info compromised operational security, fear not : the bad guys are smarter these days.
Some crew took exception to contributions by non professionals, please get off that high chair (you won't be an air jock if you were so smart) : those contributors are your "out of the box" hive of ideas improving the forum's collective neuronal bandwidth.
Thank you PPRUNE et al.
