What we didn't know at the time was that the civil engineers would have loved, needed the data as we recorded the box beams, the serial numbers, the locations, as we went into the rubble.
Wat we toen niet wisten was dat de civiele bouwkundigen graag hadden gezien, zelfs nodig hadden, dat we data hadden opgenomen over dakbalken, serienummers, de locaties, toen we het puin in gingen.
