And on the topic of aircraft losing hydraulics because of shrapnel damage, thanks to a previous accident all modern aircraft have redundancy and failsafes built into them.
United Flight 232, a DC-10crash landed in 1989 at Sioux Gateway Airport in Sioux City, Iowa, after suffering a catastrophic failure of its tail-mounted engine due to an unnoticed manufacturing defect in the engine's fan disk, which resulted in the loss of all flight controls. Of the 296 passengers and crew on board, 112 died during the accident, while 184 people survived.
Since then all airline manufacturers design hydraulic fuses that isolate systems to prevent total loss of hydraulics power, and no longer route hydraulic systems together so that the likelihood of all three systems failing is rare.
