A vertical takeoff and landing aircraft is provided including an aircraft fuselage. A register collects information regarding instructions executed by the processor, from the program counter; and a sampler, operatively connected to the register, asynchronously from the operation of the processor, samples contents of the register. The template includes a single cutting well on its proximal face over which the flexible filament is suspended. The connecting portion extends through the flat portion. When a hot drink is poured into the container body to increase the inner pressure of the container body, the fin and the side plates can obstruct the exhausting flow rate of the inner pressure so that the inner pressure cannot be exhausted rapidly.
