As most here are aware, a major part of the cache' that UFOlogists attached to GIMBAL and other popular UAP stories is the testimony of the military pilots involved in the various incidents. This arises from the public acceptance of an assumption that pilots in general and fighter pilots in particular are subject matter experts in estimating the airspeed of things outside the cockpit. The flaw in this reasoning is that they are not actually very expert in determining the speed of the aircraft they are actually flying at the time. Humans are simply not very good at judging speeds beyond the narrow range in which we and the animals around us crawl, walk and run.
Trying to find an clear example, I hit on the emergency procedures that pilots are trained to use when trying to land without a working air speed indicator. It turns out for each aircraft I was able to find training material or an online manual for, there exists a set of procedures for configuring the air craft's power settings, attitude, and flight controls so that it will naturally settle into a range of airspeeds consistent with a safe landing.

In stark contrast to Hollywood's preferred depictions, a pilot cannot just "eyeball" the correct final approach speed for a jet or most other large aircraft well enough to land successfully.
The point is clear enough, why should we accept eyeball estimates of the speeds of unidentified objects when pilots are not demonstrably much better than non-pilots in making such judgements about unidentified objects, flying or otherwise?
I found a similar pattern in a more surprisingly mundane speed regime much closer to home, people's ability to estimate the speed of moving cars and trucks. I'll have to add that later ...

In the event of unreliable airspeed indications in an F/A-18, the aircrew should follow the relevant emergency procedures, which include:
- Disengage Autopilot and Flight Directors: If the autopilot is engaged, disengage it. Also deselect flight directors.
- Rapid Descent to Below 10,000 ft MSL (in F/A-18F): Initiate a rapid descent to below 10,000 feet Mean Sea Level (MSL).
- Utilize Standby Instruments and Visual Cues: Cross-check the primary flight displays with standby instruments like the standby airspeed indicator. Maintain visual flight conditions if possible.
- Angle of Attack (AoA) as a Landing Parameter: Instead of relying solely on airspeed, consider using Angle of Attack (AoA) as a critical indicator for landing. The F/A-18's Flight Control System (FCS) can help maintain a desired AoA, particularly during landing approach.
- Pitch and Power Settings:Understanding the relationship between pitch attitude, thrust (throttle setting), and AoA becomes crucial without reliable airspeed information.
- On-speed Approach: Aim for a nose-up attitude of approximately 5 degrees, which corresponds to an AoA of around 8 degrees for a safe landing.
- Descent Rate: A good approach involves maintaining a stable descent along a glide slope (around 2.5-3 degrees), controlling the descent rate with throttle adjustments. Aim for a descent rate that doesn't exceed -1000 ft/min on final approach (-800 ft/min is optimal).
