Yeah this was the part of the story that didn't ring true for me.  No fighter pilot is intentionally going to get to such a low fuel state AND keep the aircraft in afterburner.  That's total theatrical BS but if true the guy should have his wings ripped off.

I got to Mach 2 in an RF-4C (slick configuration) over the Pacific in 1987.  I actually did it several times.  The first time we climbed the jet up to 53000 feet (max for the F-4 was supposed to be 55K and we were wallowing around and couldn't push the altitude any further) and we were in full afterburner for 15 minutes before we pushed the nose over.  The jet was at around 1.6 Mach when we started the dive and we pushed over to 45º nose low.  We went through Mach 2 at around 29000 feet but the aircraft was shuddering petty badly and we experienced a violent jolt at one point (turned out we had ripped a piece of the underbelly paneling off the jet - my Squadron CO was not pleased).

We decided to rethink our strategy because pointing the aircraft at the ground didn't seem to be the best way to do things.  We rememebered that in F-4 flight training that an aircraft will max accelerate under unloaded/Zero-G conditions.  Our next attempt we got to 53K altitude and when we were at 1.6M and the aircraft would not accelerate any more we gently pushed the nose over until we were at Zero-G and we were light in the seat.  This resulted in max acceleration in a gentle arc instead of a suicide run for the ground!

The jet broke Mach 2 aound 40K feet (no shuddering this time) and top speed on that flight according to the Mach meter was 2.2M.  After that just about all the guys in my squadron made their own successful attempts at breaking Mach 2.  We even had special patches made up to commemorate the feat that we wore for a while until the commander told us to stop wearing them.  Good times.  The F-4 was a beast!

The air blowing along the inside of an F-16 canopy comes from ... the engine.  The compressor and turbine I'm talking about aren't part of the engine, but part of a refrigeration system downstream of the compressor stages of the engine.  The heat sink for this refrigeration cycle is basically the full stagnation temperature of the aerodynamic flow.

The canopy sees this stagnation temperature only on a very limited region at the front of the canopy.  The majority of the canopy, say 80%, sees roughly 7/10ths of this aerodynamic heating.  And then, you have to factor in the thermal conduction and thermal capacitance of the polycarbonate canopy, the latter being rather significant.

The most common issue with a high flying aircraft is that the canopy is cold soaked at altitude in subsonic flight, and when descending into air with higher moisture content at lower altitudes, the inside of the canopy can fog or ice up because of thermal lag and insufficient canopy heating on the inside, and outside for that matter.  To overcome this thermal lag/capacitance, some aircraft will have heating elements embedded in the interior of the windscreen laminate.

The 16 has no heating elements. It is all done via the ECS and there are vents on the glare shield along with the manually set defog lever on the side wall it directs airflow along the inside of the canopy.

I think it's a materials thing. You can go 3.2 in an emergency intercept but things get melty in the motors.

I've heard from multiple sources including drivers here that the Mig-25 was extremely fast in real life, not just on paper.

We had an H-60:have some sort of emergency one time where it couldn’t hover to land. I don’t know what the natural winds were but I do know the Big E had 60+ knots wind over the deck and successfully recovered the helo. No, I’m not saying she could do 60 but she was absolutely moving. I’d guess ship speed was 40+ knots.

Fatty.  I was stuck on a development product line curing a new synthetic rubber compound.  Improperly vented and smoky.  Something in the smoke damaged my liver.  My weight dropped to a bit under 140.  I'm 6'2".  Doc said I was going to croak.  I thought "Fuck it, I'm getting a 750".  Every few days I'd feel goodish enough to get out of bed and go for a ride.  Off work 6 months and felt unwell for a year.    

I'd run West to East on the then new bypass of St. Marys OH between a couple of exits.  Slightly downhill and often had a decent tailwind.

I remember.  Did 72/73 cruise on the Enterprise.  High speed transit to Yankee Station from Alameda some of our escorts had to stage along our course because they couldn't keep up.   On the way home we went to the aid of a burning Liberian freighter.  Skipper (Ernest Tissot, odd I remember that) cleared flight decks, cat walks, weather decks, sponsons and kicked that thing in the butt.  It was fast.

A friend I met later in life was on one of the escorts for that cruise.  He told me when Big E went fast they had no hope of keeping up.  It may of been BS but he said on radar he's seen Enterprise go almost as fast as it's hull number.

And, from a descent starting at 50,000 feet, rather than a MAX acceleration starting at and holding 25,000 feet, and it looks like 2.0M was achieved at a more reasonable altitude of roughly 36,000 feet, which is where mission planning would take one for maximum TAS.

Yeah, the embedded heating element is more of a general and commercial aviation thing.  Fighters accomplish this via the less elegant and far more deafening use of forced-air.  The F-15 even has some defog nozzles on the outside of the canopy; I'm not an F-15 guy, so I don't know.

I didn't realize this until today, but the canopy fog/defog is actually modeled in DCS.  At least, I think they are talking about a PC sim.  Unless this greg12 dude really is a fighter pilot.  He's definitely wrong about Willie Nelson, though.

such drama.

I had the Eagle at 1.8 at 55,000 feet

there was no drama, it just went fast like it is supposed to do, no shaking, no noises, just going fast.

PSA. Bailing out at 600 knots or mach 2 isn't going to make much of a difference, your pretty much dead no matter what, same if you hit the ground, or the thing comes apart.

It's a risky game, either enjoy it or get the fuck out.
