A) they only made fixed gear warriors, arrows are retractable (and this isn't one VH-PYI)
B) q-tips weren't an option for these, yup, prop strike
C) not a collapsed right, more like a fully extended left gear as the nose was lifted
D) is there any evidence the fireys were out before it landed?
The video actually shows the aircraft being lifted off the collapsed nosewheel and both mains are equally extended.
