 Exhibit 10.4 

PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT 

THIS PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, dated as of November 3, 2021 (as it may from time to time be amended, this
“Agreement”), is entered into by and between Talon 1 Acquisition Corp., a Cayman Islands exempted company, incorporated with limited liability (the “Company”), and Avi8 Acquisition LLC, a Delaware
limited liability company (the “Purchaser”). 
 WHEREAS, the Company intends to consummate an initial public
offering of the Company’s units (the “Public Offering”), each unit consisting of one Class A ordinary share, par value $0.0001 per share, of the Company (each, a “Share”) and a fraction of
one redeemable warrant as set forth in the Company’s registration statement on Form S-1, filed with the Securities and Exchange Commission (the “SEC”), File Number 333-260305 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”). Each whole warrant entitles the holder to purchase one
Share at an exercise price of $11.50 per share. The Purchaser has agreed to purchase an aggregate of 11,900,000 warrants (or up to 13,250,000 warrants if the underwriters’ over-allotment option in connection with the Public Offering is
exercised in full) (the “Private Placement Warrants”), each whole Private Placement Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per share. 

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:
