The original SR20 Cirrus wing was bonded on to the fuselage so if it landed in a field (by normal means or beneath its parachute) it would be a game to recover. Having said that, if the BRS system had been used, the chances are it was pretty much written off when it came back to earth...
Most light aircraft are 25 ft plus long so standing it on the nose is going to play havoc with the bridges!
Cessna singles are a lot easier to move by road than Pipers which fall over when you take the wings off because of where the undercarriage attaches. That said the track on a 172 is around 8 ft which is more than your average flat bed. Tailplanes are 10 ft plus and to take the tailplane off you have to take the fin and rudder off etc etc.
There'll be alot of happy engineers now that Fly! London is Fly! Silverstone. An advantage of AeroExpo at Booker last year. Aircraft fly in, sit on a stand and fly out (even the diesel powered ones, although they weren't great at following the noise abatement turns on 06....).
