Boeing Builds Great Planes!

An enemy fighter attacking a 97th Bomb Group formation went out of control, probably with a wounded pilot then continued its crashing descent into the rear of the fuselage of a Fortress named All American, piloted by Lt. Kendrick R. Bragg, of the 414th Bomb Squadron.

When it struck, the fighter broke apart, but left some pieces in the B-17.  The left horizontal stabilizer of the Fortress and left elevator were completely torn away. The two right engines were out and one on the left had a serious oil pump leak.  The vertical fin and the rudder had been damaged, the fuselage had been cut almost completely through… connected only at two small parts of the frame and the radios, electrical and oxygen systems were damaged.

There was also a hole in the top that was over 16 feet long and 4 feet wide at its widest and the split in the fuselage went all the way to the top gunner’s turret.

B-17 Tail

Although the tail actually bounced and swayed in the wind and twisted when the plane turned and all the control cables were severed, except one single elevator cable still worked, and the aircraft still flew… miraculously!  

The tail gunner was trapped because there was no floor connecting the tail to the rest of the plane.  The waist and tail gunners used parts of the German fighter and their own parachute harnesses in an attempt to keep the tail from ripping off and the two sides of the fuselage from splitting apart.  

While the crew was trying to keep the bomber from coming apart, the pilot continued on his bomb run and released his bombs over the target.

B-17 Fuse

When the bomb bay doors were opened, the wind turbulence was so great that it blew one of the waist gunners into the broken tail section.  It took several minutes and four crew members to pass him ropes from parachutes  and haul him back into the forward part of the plane.  When they tried to do the same for the tail gunner, the tail began flapping so hard that it began to break off.  The weight of the gunner was adding some stability to the tail section, so he went back to his position.

The turn back toward  England had to be very slow to keep the tail from twisting off.  They actually covered almost 70 miles to make the turn home. The bomber was so badly damaged that it was losing altitude and speed and was soon alone in the sky.  For a brief time, two more Me-109 German fighters attacked the All American.  Despite the extensive damage, all of the machine gunners were able to respond to these attacks and soon drove off the fighters.  The two waist gunners stood up with their heads sticking out through the hole in the top of the fuselage to aim and fire their machine guns. The tail gunner had to shoot in short bursts because the recoil was actually causing the plane to turn.

Allied P-51 fighters intercepted the All American as it crossed over the Channel and took one of the pictures shown.  They also radioed to the base describing that the empennage was “waving like a fish tail” and that the plane would not make it and to send out boats to rescue the crew when they bailed out.  The fighters stayed with the Fortress taking hand signals from Lt. Bragg and relaying them to the base. Lt. Bragg signaled that 5 parachutes and the spare had been “used” so five of the crew could not bail out.  He made the decision that if they could not bail out safely, then he would stay with the plane and land it.

Two and a half hours after being hit, the aircraft made its final turn to line up with the runway while it was still over 40 miles away.  It descended into an emergency landing and a normal roll-out on its landing gear.

When the ambulance pulled alongside, it was waved off because not a single member of the crew had been injured.  No one could believe that the aircraft could still fly in such a condition.  The Fortress sat placidly until the crew all exited through the door in the fuselage and the tail gunner had climbed down a ladder, at which time the entire rear section of the aircraft collapsed onto the ground.  The rugged old bird had done its job.

Quadrocopter  Sent in by Craig. H

Quadcopter

A RC quadrocopter is an aircraft that is lifted and propelled by four rotors. Unlike most helicopters, quadrotors use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor.
100 MPH – This thing should be classified as a lethal weapon.

For those who don’t know, Torrey Pines is a state park and launch site for paragliders in San Diego , California . Occasionally these paragliders bring along some special friends.This is a cool video! Before video starts, be sure to go to the bottom right of window and click on “Watch Full Screen Icon”.

These last three are from Otto D.

Thought you’d enjoy the latest $8 creation (less electronics). The plane weighs 3.5 pounds with 7 pounds of thrust and just over 11 sqft of wing.

The Prez’ Sez’ for January 2012

Frank IndoorI’ll start by thanking all the members of the SEFSD for entrusting me with the honor of guiding the club for 2012.
I’ve been in this wonderful hobby/sport since 1947 but I’m just a beginner compared to most when it comes to electric flight. We have a wealth of talent in our club and if you don’t tap it you do your self a disservice. Remember………………None of us know it all!…..
I have some ideas that I’ve brought to the Board of Directors for goals for 2012 that I’ll present at the next regular club meeting on Jan 28th, 10 AM at the Mission Bay field.  PLEASE  try to attend.

First and foremost will be the improvement of our field. Many people are giving of their time, talent and treasure to make it better than ever……….WE WILL GET THIS DONE.

Next is safety…………I’ll be giving you my thoughts as will the rest of the club officers. If you want to input YOUR ideas………………attend meetings.

Before closing, a thank you to Mike Eberle for spearheading the indoor flying sessions. I attended the latest one on the 24th and I assure you indoor is alive and well and a blast!

Thanks you again……………….When I’m at the field say hello…….and if you’re wearing your cool new name badge I’ll know who you are………less the “senior moments”…….

Typically dispensary can offer to customers with convenient treatments for variant diseases. With the Internet flooded with various online drugstores selling variant remedies, purchasing medicines online is no longer a dream for most of us. You can order online drug to treat chronic treatment of the symptoms of rheumatoid arthritis or spasticity. Few medicaments are used to treat impotence. Cialis is a preparation prescribed to treat a lot of afflictions. What do you think about best place to buy generic viagra online? Where you can read correct info about ? (Read more ). Perhaps you already know slightly about the question. Ordinarily when something goes wrong with your erection, it can exert your sex being as well as your overall well-being. Once you’ve studied the basics about men’s erectile malfunction from us, you may want to see what other reputable sources have to say. Online pharmacist services are the only safe variation if you are going to get remedies, like Cialis, online.

Indoor Flying for Jan 2012

January saw an excellent turnout for both indoor flying dates.  Here are some pics from Jan 24th.  Of special note was C.M. Kim’s completely home made micro planes.  Please see the article under “Indoor Pilots & Planes“.  Also we saw a fully lit quad copter controlled by a smart phone!  Frank directed a pylon race for the Vapors and Embers plus another for the usual gang of micro racers.  Check out the photo gallery here.
