It can be done sanely, but they don't have anything flying yet (was supposed to be May 2017 but that came and went).

Also, don't be fooled. The smaller test aircraft, if it ever flies, will have a much lower sonic boom than the larger airliner. Sonic boom is largely proportional to aircraft weight.

Reading between the lines it would appear that they are so far from having anything that flies that they're still willing to redesign their engine and presumably plane as a result.

(And yet they have the hubris to talk about how much a ticket will cost)
