Wreck of a Schiphol airport crashtender (1969-1984). Schiphol needed a recovery vehicle that was capable of crossing the ditches that were on the airport terrain. The airport firebrigade found three used M4 tractors from #WW2 in a US Army dump in Cologne which were converted. pic.twitter.com/vEdBCpqJeB
