Is it true that SpaceX uses pyrophoric igniter fluids like triethylaluminum-triethylborane to ignite rocket engines?

Yes. The claim that SpaceX uses pyrophoric igniter fluids like triethylaluminum-triethylborane (TEA-TEB) to ignite its rocket engines (such as the Merlin engines on the Falcon 9) is a matter of common knowledge and aerospace engineering fact, supported by technical literature on TEA-TEB ignition properties.

Verdict: SUPPORTED · Common knowledge · 1 source for, 0 against · Last checked

The analysis

The claim is a well-established technological fact regarding SpaceX's engine ignition systems (specifically the Merlin engines). Paper [10] directly discusses TEA and TEB as pyrophoric liquids used as hypergolic rocket propellants and their ignition behavior, supporting the chemistry of the claim. Because this is a well-known technical fact of everyday observation in aerospace engineering, the verdict is COMMON_KNOWLEDGE, with supporting evidence cited.
