What are two bits of experimental evidence that supports the special theory of relativity and how?

And who thinks there are only two? There are dozens if not hundreds of experiments that support the STOR. Here are but a few:
1. Time dilation is observed when flying commercial aircraft. Two synced atomic clocks are checked after landing and the one on board the plane is slower by nanoseconds than the one that stayed on the ground.
2. Decay rates of radioactive particles accelerated to near light speed in accelerators slow down when measured by an observer's clock outside because the observer's time is stretched relative to that of the particles.
3. Communication satellites must transmit at higher frequencies than the receivers on Earth are set to receive because satellite transmitting periods are foreshortened by time dilation.
4. Particle accelerators must compensate for the increases in particle inertia as the particles are accelerated up close to the speed of light. That is the accelerating force is F = Ma where M is relativistic inertia.
The STOR is a fact of engineering fact. It's not just some abstract theory. So there are dozens of examples where the STOR is shown to be valid. Anyone who thinks there are but two doesn't know the STOR.

The very first puzzle which kind of kicked of the whole issue was the Michelson Morley experiment to measure the speed of light through the aether as the Earth rotated on its axis and orbited the sun. It rather confounded everyone by always measuring the local speed of light to be exactly the same regardless of the time of day or year, as if there wasn't an aether.
The decay time of mu-mesons produced by cosmic rays at close to the speed of light can be measured on Earth. The decay time appears to be far too long unless you factor in time dilation.
