Taking into consideration the recent air plane disaster, how many major airline planes worldwide have completely disappeared or never been found, following air incidents?

While numerous aircraft have disappeared without a trace, (The NTSB lists about 200 of them in the past 47 years, and those only affect U.S.-involved incidents) none can really qualify as being a "major commerical airline" or left zero traces at all. The vast majority were general aviation craft. The below link lists only major commerical aircraft accidents: http://en.wikipedia.org/wiki/Lists_of_accidents_and_incidents_on_commercial_airliners Several notable incidents include: The Southern Cloud, which disappeared in Australia in 1931 and was undiscovered for 27 years; A 1947 Andes crash that was not found until 2000; A 1950 Northwest Orient flight crashed into Lake Michigan and although considerable debris was found, the aircraft itself has never been recovered; A 1957 Pan Am liner went down between San Francisco and Hawaii, small bits of wreckage were recovered a week later by the Navy.

Incidents involving missing commercial flights, but not on major airlines, that have "vanished without a trace": Hawaii Clipper July 29, 1938 vanished between Guam and Manila: http://dotlibrary1.specialcollection.net/scripts/ws.dll?browse&rn=73&dh=1&lrn=11&fi=0#WSH0 Pacific Alaska Air Express vanished November 4, 1948 between Alaska and Seattle: http://dotlibrary1.specialcollection.net/scripts/ws.dll?browse&rn=418&dh=1&lrn=35&fi=0#WSH0 Airborne Transport vanished Dec 28, 1948 between San Juan and Miami: http://dotlibrary1.specialcollection.net/scripts/ws.dll?browse&rn=423&dh=1&lrn=37&fi=0#WSH0 Flying Tiger, which operated as a military passenger airline, vanished also between Guam and Manila March 15, 1962: http://dotlibrary1.specialcollection.net/scripts/ws.dll?browse&rn=738&dh=1&lrn=13&fi=0#WSH0 Kodiak Airways vanished Dec 11, 1974 between Old Harbor and Kodiak, Alaska: http://www.ntsb.gov/ntsb/brief.asp?ev_id=41236&key=0 I should add that those incidents above of "vanishing without a trace" were only from the CAB files so they only involve incidents involving U.S carriers or locations; the wiki link at the top lists all worldwide incidents, but again none of them qualify as having "never" been found.
