“Passengers should not worry,” Reassures the People’s Daily

Tape

From the article accompanying this picture, "Lu Xiang, who teaches aircraft
maintenance at the Civil Aviation University of China, said it is safe
to use aluminum tapes to fix things on a plane temporarily, but not as
a permanent solution.

Passengers should not worry, because
before every take-off, planes need a nod from qualified professionals
who thoroughly check their condition, he added."
