How to best shoot down a Helicopter ? the enemy worked on this hard an found out the best time to get one is on landing or take off they also perfected a .51 caliber machine gun with Aeriel sight that had the necessary velocity to reach an in flight Helicopter of say a height of 400-500 feet at 70 knots , Looking out many times I've seen tracers reaching out to us , those coming straight at you ignore your speed would put you past that point even those that were leading you ignore because the average AK-47 did not have velocity to stay on a flat trajectory , but the .51 bullet had the power to stay on a flat trajectory for close to 700-800 feet .

I though they just aimed at a point in front, and then the chopper just flew into the stream?

That's what many people think about it but you have to take the trajectory into account which is determine by weight of bullet and gravity the higher the bullet is amied the more gravity is pulling on it , say you're at 500 hundred feet the shooter is leading you the gravity starts pulling the bullet down at 100-150 meters + you're moving between 60-70 knots there is not much to worry about , unless the bullet is a .51 caliber gravity doesn't start pulling it down for 300-400 meters , if you see a tracer coming at you that's looks the size of a soccer ball you're in trouble .

With a rocket launcher, and the round must have armor-piercing capability.

The enemy had the RPG-7 which was superior to anything the Americans had in close up Rocket Launcher it was lite very portable easy to maintain it one flaw do the type of fuel that propelled the thing it left a vapor trail that lingered 4-5 seconds which can be dangerous to the person operating it . What was needed to bring one down was a high velocity shell with a flat trajectory of at least 700 ft and the NVA had that with their .51 .

Being shot down is an uncomfortable feeling but there were many other factors that could bring a Huey down , the mechanics of a helicopter are a wonder , what keeps the damn things in the air even the experts are sometimes puzzled .

One theory is that they are so damned ugly and noisy that they are rejected by the earth..... (Sort of an anti-gravity thing....) |

Yes a swarm of Huey's from a distance look like tadpoles , the enemy always knew you were coming from the whomp whomp of the blades until some genius might have an officer but doubtful came up with eagle flight , tree top level 3 klicks ( km ) out a fish hook type of maneuver , it made your testicals tingle to be that close to the ground 20-30 ft. at 80 knots .

Why do you need AP to shoot down a Huey?

Folks drive cars closer to the ground at that speed all the time. "Course there are very few times anyone is shooting at them....except in Chicago... |

Tail rotor failure , what happens when your flying along enjoying the view and the tail rotor quits working , well the whole ship will spin around and round right down to the ground another good reason you had to be crazy to crew one of the things .

Tail rotor failure would not be fun no matter whether you were 20 feet, 200 feet, 2000 feet or 20,000 feet above the ground.....
I doubt that it would make my testicle tingle but I'm sure I'd be biting holes in the seat....

Yes I saw a Huey lifting off from a refueling point the tail rotor failed they had just gained about 20ft the Huey went side ways the main rotor hit first by the end of it the Huey looked like a scrap pile two men killed two men dust-off the whole thing took about 10 seconds one man had the top of his head taken off , there lay the top part of his head in the top part of his helmet brains and shit just sitting in the helmet like some gruesome meal . but the war continues and instead of ten Huey's we took off with nine .

I just watched one of those Vietnam war movies and was wondering what the best landing formation for a hot zone was. With the two door gunners I guess landing in line might have been the best to avoid unwanted damage from other door gunners and only the first and last helicopter in danger from the front or back. Is there a publication for that? Has this approach changed in the past years? I guess the problems are still the same, even when they fly now the Blackhawk instead of the Huey.

This touches on a subject re B17s defending against the German fighters.
The USAAF records show that these bombers expended 12,000 rounds of .50 cal for every plane claimed and awarded. Given a huge number of bombers, and a huge number of 'door gunners', shooting a huge number of bullets, I would bet that the over-claims would also be huge.
Nobody has ever been game to estimate how many B17s were shot down by 'door gunners'.
Except gunners from TN, who could not hit the side of barn at 50 feet.
