Back from vacation! Sheldon Adelson’s chariot for high rollers! At Boston Logan for just an hour (notice this speed demon uses the entire runway to land!), I did not recognize this plane and one of my wonderful – and expert aviation friends gave me the low down! Thanks Phil and here it is, for those of you, like me who are still learning:
SP Stands for “Special Performance” with a shortened fuselage, lower weight, therefore lower fuel consumption and greater range. 50 were built between 1976 and 1982 (approximately) with Pan Am, South African, and QANTAS being among the main customers for their long-haul routes. Other operators included American, TWA, United, Braniff, Aerolineas Argentinas, Air Namibia, Air Malawi (just one flight) and probably a couple of dozen other carriers large and small.
