33 engines. There’s no way to achieve the thrust necessary with one engine. They will achieve success, watch.

You CAN achieve that much thrust with fewer, more powerful engines:

Saturn F-1: 1.75 million pounds of thrust each.

Falcon: 0.53 million pounds of thrust each.

The Saturn V never failed to launch. Ever.
