   "Boom Supersonic Completes XB-1 5th Flight With Speeds Of Mach 0.69"
   "XB-1 is intended to be a proof of concept" for the Boom Overture airliner scheduled for 2030

   But MIT "concluded new supersonics would burn 3.2 to 10 times more fuel per passenger-mile" and "would still produce sonic booms"

   And...JAL invested $10M with "option to purchase up to 20 Boom aircraft" with only enough range for Tokyo-Honolulu or Seattle.🤡

     Also learnt that JAL invested $10M with "option to purchase up to 20 Boom aircraft" in 2017.
     Revised specs of the Boom Overture aircraft state operation by 2030, Mach 1.7 max speed, and range of 7,870 km which is enough for Tokyo-Honolulu, but not for Tokyo-LA

     Memories of JAL's options on Concorde in the mid-60's & cancellation due to noise & business realities don't seem to have been passed on within the company...so history repeating itself😓
