Flaw or Tear?

I found something interesting in recent ebay listing, the 5R value of 1946 King George VI stamp has obvious white strip.   The strip cross the King's face from nose to mouth.  It is unclear from the photo uploaded by the seller, but I tried my luck to explore more of the strip, flaw or tear.

When the item arrived to me, I takes the microscopic photos of it and did analysis.  Based on the close up photos, it is assumed as a flaw.  One more analysis to do is to use electronics watermark detector to check the thickness of the stamp paper.  If it has same thickness throughout the stamp, it can be confirmed that as a flaw.  The close up view is displayed below.

Burma Aerogramme found in BOAC "Comet - York Peter" Crash, 1954

The B.O.A.C flight 781 crashed near the Elba Island, Italy on 10 Jan 1954.  The comet was operating the flight from Singapore to London via Rome where it made a stop at 10:30 AM.  20 minutes after take off, from Ciampino airport, the aircraft crashes take place when the Comet broke up in the air, near the Elba island.  All occupants were killed in the accident. 

  

The following day postal bags were recovered by a fishing boat and taken to Genoa by the steamer “Persia”.  The recovered mail bears several different cachets depending on the destination. Covers and aerogrammes sent from Burma to UK were found in these mails.  The aerogramme highlighted below is sent from Rangoon addressed to Scotland.
