On this day in 1950, a Bell 47 helicopter did something no helicopter had ever done: it flew over the Alps. The date is preserved in the type's aviation histories — 'it became the first helicopter to fly over the Alps on September 21, 1950,' as European Airshows' chronicle of the Bell 47 records it.

The machine deserves the headline as much as the flight. The Bell 47, designed under Arthur M. Young at Bell Aircraft, had in 1946 become the first helicopter in the world certified for civilian use — the bubble-canopied, lattice-tailed silhouette that practically defines 'helicopter' in the mid-century imagination. A year before the Alps, a Bell 47 had set an altitude record above 18,000 feet; two years after, one would fly 1,217 miles nonstop from Texas to Buffalo.

An honest note for the record: the surviving accounts preserve the date and the aircraft, but not, in any source we could verify, the pilot's name or the exact route across the mountains. History sometimes files its firsts incompletely. What stands is the fact: as of this day in 1950, not even the Alps were beyond the reach of rotary flight.

Also on this day

  • Gen. George C. Marshall was sworn in as US Secretary of Defense.
  • In Korea, US Marines fought through the western outskirts of Seoul.

🎵 On the radio that week: America’s No. 1 song was “Goodnight Irene” by Gordon Jenkins and The Weavers (Billboard best sellers) — TIME magazine sniffed that the Weavers' polished version was 'dehydrated' and 'prettied up' — America bought it anyway. That sound never really left — we recreate 1950s doo-wop and slow-dance ballads every week: read the stories behind our songs or listen on the lovesong1950s channel.
🎬 At the movies: “My Blue Heaven” held the nation's No. 1 spot for a second straight week, with “Sunset Boulevard” right behind at No. 2 (Variety).
⚾ In sports: The AL race was a dead heat for the ages — Yankees 90-53, Red Sox and Tigers both 89-53 — while the Phillies reached their high-water mark: 7.5 games clear with two weeks to play.

Postcard Heart – The 1950s Doo-Wop Love Letter That Never Needed a Stamp v.21

Image
Story Behind the Song · Postcard Heart , Track 1 ▶ The player starts right at this track (00:00). Let it keep playing for the full album. He only meant to buy a postcard. Blue sky, a little red canoe — the kind you send to someone far away with a line like "wish you were here." He was still writing it in his neatest hand when she walked past the postcard stand, and suddenly there was no faraway town worth wishing about. That is the whole heart of this song, and of the album that takes its name from it. The doo-wah harmonies bounce like a stamped envelope skipping across a mail sorter, while the lead vocal keeps one hand on the counter, half in love already. By the second verse they are taking the long way past the square, and a small heart drawn next to a name has quietly re-addressed his whole life. If you have ever mailed your feelings to the wrong distance, this opener sets them straight: the only address that matters is standing right in front of you. I...

August 23, 1950: The Flood After the Great Assam Earthquake

Today in 1950 · Wednesday, August 23, 1950 Crew on the deck of a Brahmaputra River steamer, Assam region, 1895 — the river basin devastated by the 1950 earthquake · William Henry Jackson, Library of Congress, public domain, via Wikimedia Commons In late August 1950, the aftermath of one of the strongest earthquakes ever recorded was still unfolding in northeast India. The magnitude 8.6 Assam-Tibet earthquake of August 15 — among the ten most powerful instrumentally recorded quakes in history — had sent enormous landslides into Himalayan river valleys, damming rivers including the Subansiri. About a week after the quake, the natural dam on the Subansiri burst. An eyewitness account preserved by the Assam Times records that the river 'remained blocked for five days' before a midnight flood surged through with twelve to fourteen feet of water, obliterating everything in its path. In the villages of Torajan and Ghasigaon, the account says, there were no survivors — not even...

The Story Behind the Song · The Orioles, 1953 The Orioles in an early press photo by James J. Kriegsmann, taken before 1954 · Shaw Artists Corporation, published without copyright notice, public domain Who wrote Crying in the Chapel? Artie Glenn wrote "Crying in the Chapel," first recorded by his son Darrell Glenn on Valley Records. The Orioles recorded their version on June 30, 1953, and Jubilee released it that July. Their recording became a No. 1 R&B hit and crossed over to the pop charts. The Orioles’ Crying in the Chapel: the 1953 charts What happened next is the part worth remembering. By the Billboard issue dated September 5, 1953, the Orioles' record stood at No. 1 on both of the magazine's rhythm-and-blues charts at once — National Best Sellers and Most Played in Juke Boxes. A week later it was No. 11 on the pop Best Selling Singles chart. And it was not alone there: on a single page of that September 12 issue, four different versions of the sam...
