Interesting to know, how they know it considering the fact, that pressing an unarmed GA button is not recorded anywhere.
Knowing,
a) that after the go-around command, for a period of 4 seconds there was no input on wheel or engine throttle nor was the ABSU disconnected
b) that in the 36th regiment check flights for non-precision ratings where conducted most of the time in ILS approach and therefore automatic go-around was probably best practice,
c) that the PIC explicitly briefed the crew about his decision to do go-around in automatic mode in case of missed approach
it is quite valid to conclude that the PIC (or 2nd) did actually press the button.
Furthermore in absence of relevant flight recording data, there is nothing that could prove to the contrary.
