There are a couple of companies working on smaller supersonic jets that might have reduced sonic boom performance thus allowing overland operation. Possible market for supersonic business jets but for general aviation the economics don’t work. The new Bombardier 7500 has a claimed specification of 0.925 Mach with a 7700 nm range.
Confirmed: Bombardier’s Global 7500 Aircraft Breaks Key Speed Record Between Los Angeles and New York

It has another record for the longest distance flown by a corporate jet, at 8152nm (and still had 1.5 hours of reserve fuel): Global 7500 Sets Bizjet Range Record

A very interesting restoration and unique project at the Flying Heritage & Combat Armor Museum in the US with some background on how these projects work.

I don't think a better explanation of the MAX problem can be found anywhere! This is a superb article. It also highlights some of the problems with engineering new high tech products, both hardware and software.

Both Airbus and Boeing were hard pressed to counter the emerging threat of the C-Series to their midsize business due to demands posed by their larger new jet programs. Both companies opted for updates on their older designs (A320 and 737) in order to quickly restrict Bombardier from getting a slice of this key market segment and they were successful at doing this. In Boeing's case, as the author notes, the Boeing upgrade produced a flawed aircraft from a hardware prospective. Economics forced a software solution and we now know how
that worked out. It will be interesting to see how long it takes for the FAA to re-certify the MAX and what new requirements will accompany its reintroduction. Will the FAA take another look at the A320neo?

Bombardier is downsizing. Not really a surprise after their C-Series missteps, and bad timing. They dithered on the start-up and missed the optimum delivery opportunity (before Airbus and Boeing could offer alternatives). The collapse of oil prices and PW geared turbine issues didn't help either. I am not a fan of the family management team. Although the business jet product range is solid, some of there rail operations suck, e.g. Toronto street cars. I guess as a smaller operation, there will less pressure n future governments to bail them out with corporate welfare.

Another negative story on the 737 MAX. If this had happened 2 years earlier, would Bombardier still own 100% of the C-Series? Can Airbus increase its NBA market share? Probably not as in Airbus’s case, they couldn’t handle much more volume. Boeing should be thankful Chinese commercial vendors can’t fill the gap. However, after this fiasco, airlines considering a 757 replacement will be giving the Airbus 321neo a closer look thus jeopardizing Boeing’s 757 replacement prospects IMO.

Long before first 737 MAX crash, Boeing knew a key sensor warning light wasn’t working, but told no one

Boeing has completed testing on its software fix for the MAX and is now discussing recertification with the FAA. After the grilling the FAA chairman got during Congressional hearings yesterday the recertification process this time around is likely to be very comprehensive.

Boeing completes software update, tests for 737 Max
The software fix might be the easy part. Now they have to repair the enormous amount of damage they have done to their brand.

Indeed, a real uphill PR climb ahead. Wouldn't be surprised if some potential 777x customers take a wait and see timeout before buying.

Talk to some people from Garuda..which already in negotiating with Boeing on cancellation of MAX..their option are:
1. Changing their order to other Boeing airplane..with talk on 787 for their regional routes.
2. Maintain their 737 800 for few more years than plan, while wait for delivery slot on A320 or A220 for replacing their local/national routes.

They can go either way or combination of both options. But yes, it's the damage reputation of MAX that make several loyal 737 customers thinking in ditching it on their future plan.

Garuda is the only one so far that already officially stated they are ditching MAX. However, I understand there are several other airlines (that used to be 737 loyal customers) on talk with Airbus on 320 or 220 as alternative. Personally, I do tend 220 will become attractive alternative..since 320/321 backlog orders already long.. while Airbus is building new facility in US for 220 that add existing Bombardier facility for 220.
If not mistaken in term of capacity and range, 220 is closer to either MAX or 320 compared to E series.

Wondering if China or Russia new narrow bodies can take advantage on this too. Doubt it can take much outside Chinese or Russian Airlines..but if these 737 MAX saga continues to second half of this year..well you never knows.

Boeing perhaps should speed up 797 as their alternative to MAX.

Rolls Royce have taken a bit of a hit. Air New Zealand have where possible always powered their aircraft with Rolls Royce engines. When the acquired their 13 Boeing 787-9 Dreamliners they had the RR Trent 1000 powering them. They've had a gutsfull of the Trent 1000 and all the problems that it has caused them, costing them about $25 million so far. Now they have ordered Boeing 787-10 Dreamliners to be powered by GE nx1-B engines. These aircraft are replacing eight Boeing 777-200s powered by RR Trent-800s.
