You can now fit a paperback sized complete blind flying panel in your Ultralight / Homebuilt which has solid state gyros and (I think) GPS built in. As the "statistically impossible" has now occurred, maybe the powers that be should be thinking about fitting these, or even providing them as a Quick Fit unit complete with a long life primary battery, stored somewhere readily accessible. This would give the crew a much better chance of locating a suitable runway even if they did have to put it down wheels up.
