Watch a huge remote-control plane meet a crashing end
Commentary: The Junker JU-52 has an 20-feet wingspan. But just before it lands, its engine appears to stall. And then, calamity.
Technically Incorrect offers a slightly twisted take on the tech that’s taken over our lives.
Seconds before disaster.

It takes time to put them together.
Not a little love, too.
When you’re done, you watch your creation fly like a big bird. Well, a big bird that hums a lot.
In this case, the big bird is the one of the biggest remote-control model planes around — the Junker JU-52. Its wingspan is 6.09 meters (almost 20 feet). From nose to tail, it’s 4.07 meters (13.4 feet).
And as a YouTube video that’s been pulsing around the web this week shows, it’s fun to fly. The JU-52 soars over green fields under a blue sky, apparently at a meetup of model airplane fans in Germany.
At takeoff, it looks just like so many private planes you’ll see rising from your local airport.
It seems to maneuver successfully at some height. You’d think you were at an air show.
Toward the end of the 8-minute video, the Junker comes in to land. All seems serene. The wings level out.
Then, within inches of the ground, the plane lifts a little and yaws to its right. The propellers cease spinning.
More Technically Incorrect
Lurching further, it crashes in a heap, its tailpiece shearing off and striking a parked car.
On YouTube, commenters — some who might even know what they’re talking about — weighed in to offer their judgments. Some immediately lurched to the right and blamed the pilot. Others insisted that bad things can happen to good pilots and that it’s impossible from the video to tell what happened.
For me, the Junker’s demise is all too redolent of people who spend weeks, months and even years building things, only to see them destroyed in seconds.
It’s the same principle for an Elon Musk rocket as it is for a meticulously built old German model plane.
All you can do is learn from what happened and then rebuild the thing and try again.

Chris hi! This amp is already a bridge and powerful enough for a city bus . This amp already boost the supply voltage to approx 22 volts.
Another comment poor old alternator must feed 4 x 100 watt globes plus 2 times 50 watts and the battery must also be charged and then all the other gadgets you may have in that car!! This is the reason why batteries and alternators do not live as long as they should you are overloading it and this power come from your engine and hence fuel.I have had this on a car in 1972 that the battery had to be charged regularly and did not even outlived its warranty period and the seller and manufacturer denied warranty claims
