Can a plane land on an aircraft carrier without support from its crew?
The Nimitz Class aircraft carriers are the largest warships ever built. With over 6,000 personnel (crew and aircrew), the carrier has a displacement of 102,000t, and a flight deck length of 332.9m.

332.9m * 39 in/m * 1 ft/12in = 1081.9 ft.  I think many small (2-4 seat) aircraft could land &amp; stop in that distance. I'm pretty sure I could in my Cessna 177B, fixed gear, with micro-vortex generators for slower landings. Even without any headwind to help slow down.

From the 177B Pilot Operating Handbook:


  LANDING PERFORMANCE:
  Ground Roll    ---------------------------------------------------- 600 FT


And that was before the micro VGs, so it should be even shorter now.
