John and Doves,
 
In his letter Friedrich quoted the Airbus A380 as having 555 seats. Interestingly this is also the height in feet of the Washington Monument or obelisk. 555 feet = 6,660 inches.
 
It could be said that 555 seats = 555 (pairs of) feet.
 
555 x 2 = 1110 = 3 x 10 x 37.
 
555 is also 3 x 5 x 37.
 
Blessings,
 
Phil.
