I think such quips are probably unfair on Flyingmac; the way I read it, his witness was probably ground or indeed other air crew who learned the readings afterwards; that scenario should hardly come as a surprise...
I'm presuming the Tucano ( never played with them myself except very briefly during the aircraft selection competition ) has some sort of recorders, or it wouldn't be much of a trainer; anyway the various bent bits should give a good clue !
