My current ride is way cool but from the memory banks;
Grumman AA-5. Canopy slid open on a hot day was like cruising in an old american convertible. For those that know him, ask the ex NZGS fish spotting legend why he's kept his all these years!
Bandeirant - my first 'big aeroplane'. Tough and fun - except at NZWR on a hot day!
Nah that was fun!
737-200 - Legend!
Overall favourite?? My 'username' comes from its engine power
-- the Beech 1900D. Brilliant!!
