ahh... a topic after my own heart.
i adore 'planes too, throughout the ages. living near two big aircraft museums both in england and delhi has been a fulfilling experience indeed. my favourite sounds of melodious albion have been the roar of merlins as the spits and mustangs fly over our garden in the summer airshows. this year we even had a me 109 (yes, a spanish remake), following a vic formation of spits!!!
i can't pin down any favourites, i love too many aeroplanes. however, aesthetically speaking the aircraft types i love the lines of and have enjoyed modelling again and again would be:
Commercial
Till 1950s: the tante ju............i love it! i'm waiting for the swiss flights to start again
50s-late 70s: the super connie. specially in lufthansa livery
Late 70s onwards: nothing....nobody remotely close to a constellation IMHO
Military Combat
WW1: The albatross DIII-DV, i must have done more models in more colours, and am going to work on another pair this weekend
WWII : the spits are beautiful, though me109s have more variety, hence my preferred subject (specially the Es and the Gs)
jets: ooooohh baby..........the F 104 starfighter
