I highly recommend watching the related episode of "Mayday" Air Crash Investigation about Tenerife. Hulls are so fragile that they've often shred up in flight (De Havaillan, DC-9). Landing is around 200-250kmh only, but planes have caught fire just sliding on runways or terrain. The quantity of jet fuel immediately means catastrophe.
