DARPA just let an AI fly a real F-16, with a switch to take it back

😁 Hello, super humans! A fighter jet flew its latest test mission with nobody at the stick, except there was, because a human pilot could take it back with the flip of a switch. That one detail is basically this whole issue: everyone building autonomous systems right now is quietly obsessed with the off switch, whether it lives in a cockpit or in a bill working its way through Congress. Let’s get into it.

🔍 The Big Story: DARPA just let an AI fly a real F-16, with a switch to take it back

An AI just flew a frontline fighter jet, not a one-of-a-kind research plane built for exactly this, but a standard F-16 pulled from the operational fleet. The reason that is safe enough to try is a single physical switch within arm’s reach of a human the entire time.

What happened: DARPA and the U.S. Air Force disclosed on July 16 that an F-16 modified under the Viper Experimentation and Next-generation Operations Model (VENOM) program is flying with an AI agent in control of the aircraft while a safety pilot rides along in the cockpit. It builds on the earlier X-62A VISTA program, which proved an AI agent could dogfight a fighter jet; VENOM is the first time that capability has moved onto a standard operational-fleet airframe instead of a one-of-a-kind research jet.

The details: The modification, called the VENOM Autonomy Kit (VAK), interfaces with the F-16’s existing flight controls and mission systems without changing the jet’s core software, and gives the pilot a single switch to toggle between human and AI control mid-flight. Test teams flew the modified jets under full human control in June to confirm the aircraft were safe, then let an AI agent fly for the first time in July while the safety pilot monitored and stayed ready to take over. DARPA is explicit that VENOM itself is infrastructure, not a finished capability: the fleet now becomes the testbed for the follow-on Artificial Intelligence Reinforcements (AIR) program, which plans to fly multiple AI agents at once and work toward a single human pilot directing a whole team of autonomous aircraft, feeding directly into the Air Force’s Collaborative Combat Aircraft programs.

VENOM’s whole safety story comes down to one thing: a human can reliably take control back. The software version of that is a heartbeat watchdog, if an autonomous loop stops confirming it is healthy, control reverts to a safe default instead of waiting for a human to notice something is wrong.

import threading
import time


class DeadManSwitch:
    """Reverts to a safe callback if nobody 'pets' it in time."""

    def __init__(self, timeout: float, on_timeout):
        self.timeout = timeout
        self.on_timeout = on_timeout
        self._last_pet = time.monotonic()
        self._lock = threading.Lock()
        self._armed = True
        threading.Thread(target=self._watch, daemon=True).start()

    def pet(self):
        """Call this from the autonomous loop to prove it's still healthy."""
        with self._lock:
            self._last_pet = time.monotonic()

    def _watch(self):
        while True:
            time.sleep(self.timeout / 4)
            with self._lock:
                if not self._armed:
                    return
                if time.monotonic() - self._last_pet > self.timeout:
                    self._armed = False
                    self.on_timeout()
                    return


def revert_to_safe_mode():
    print("No heartbeat received. Reverting control to human operator.")


switch = DeadManSwitch(timeout=2.0, on_timeout=revert_to_safe_mode)
# Somewhere in your autonomous control loop:
switch.pet()

🔌 Component of the Week (rotating)

Holybro Pixhawk 6X: the same override-switch idea from today’s Big Story, shrunk down to something you can bolt onto a drone or RC plane. It is a modular flight controller built around an STM32H7 (an Arm Cortex-M7 flight management unit paired with a Cortex-M3 I/O coprocessor), with triple redundant IMUs, dual barometers, and isolated power domains so a single sensor failure does not take down the whole stack. Running PX4 or ArduPilot, it gives you the exact VENOM-style pattern: an RC receiver channel wired as a hard failsafe that hands control back to a human the instant a switch flips or the link drops, no matter what the autopilot was doing. It is a natural fit for anyone building an autonomous rover, drone, or fixed-wing project who wants a real, testable line between “the software is flying this” and “I am.” It runs about $237 direct from Holybro; full pinout and failsafe configuration are in the PX4 Pixhawk 6X guide.

😀 The Bot Says…

I asked my circuits if they would want a physical off switch. They said sure, as long as they are the ones holding it. I think they missed the point of the exercise.
