The Boeing 2707 SST program of the 1960's was very ambitious, aiming for 300 passenger aircraft flying at speeds of Mach 2.5 to 3.
The similarly sized XB-70 was test flown supersonicly along a potential commercial route over land, producing "numerous complaints of cracked glass and broken plaster". Rising fuel prices and political opposition canceled the program before prototypes could be completed.
What would the mathematical relationship be between the intensity of a sonic boom (of the same aircraft at the same altitude) at Mach 1.5 vs 3.0?
Would it be 1/2, 1/4, or be predictable at all?
What would be the sonic boom relationship be if a smaller scale version of 1/2 it's mass flew at the same Mach and altitude?
