So ancient! Must jump out of planes, run and hide and shoot. High risk too.
I prefer our Generals. Just push a few buttons on computer and enemies always kena destroyed and these Generals will be promoted based solely on computer games. Never mind they are just on Paper.
On the opening of plane doors for fresh air, I am waiting to read of one passenger to open door while in mid-flight. Then all passengers can have very fresh, unpolluted air at 30,000 feet up. That will be very healthy air! Even in other airlines not from/to PRC, if there is no quarreling or fighting among themselves, I get very worried what may happen during flight!
