In J. R. R. Tolkien's legendarium, fëa and hröa are words for "soul" (or "spirit") and "body". The plural form of fëa is fëar (pronounced [ˈfɛ.ar]) and the plural form of hröa is hröar (pronounced [ˈrɔ.ar]). (The words are also spelt fea and hroa because the spellings ëa, öa, where they occur, are only meant to remind people used to English orthography that the two vowels should not be drawn together in speech as in English "sea" or "load")
The Children of Ilúvatar (Elves and Men) are described as existing as two parts: they have a "spirit" or "soul" called fëa, and a body or hröa which is made out of the matter of Arda (erma); for this reason hröar are Marred (or, using another expression by Tolkien himself, contain a "Melkoringredient"), and this explains also why it was easier for Melkor and his servants to seduce Men rather than Elves, because mannish fëar have much less control of their hröar. According to the Elves, the fëa is powerless without the hröa, and likewise the hröa would die without the fëa.
F♯ A♯ ∞ (pronounced "F-sharp, A-sharp, Infinity") is the debut album of the Canadian post-rock band Godspeed You! Black Emperor. It was released twice, first in 1997 by Constellation Records and then again on 8 June 1998, by Kranky as an expanded edition that ran for 63:27. The album is devoid of traditional lyrics and mostly instrumental, featuring lengthy songs segmented into movements and wide dynamics.
The album was recorded at the Hotel2Tango in the Mile End of Montreal. It was initially released in very limited quantities, and was mainly distributed through live performances and advertised by word of mouth.
In 1995, Mauro Pezzente moved into a loft with his then-girlfriend in the Mile End of Montreal. Pezzente used the flat as a performance venue, dubbing it the Gallery Quiva. Around 1996, fumes from the mechanic's garage below the loft forced them to vacate it. Shortly after their departure, Efrim Menuck moved into the space and established Hotel2Tango, serving both as a recording studio and practice space. There, in 1997, the original recording of F♯ A♯ ∞ took place. By this time, the band had reached an unwieldy 15 members. In preparation of the album, they trimmed their numbers to ten.

The Northrop M2-F3 was a heavyweight lifting body rebuilt from the Northrop M2-F2 after it crashed at the Dryden Flight Research Center in 1967. It was modified with an additional third vertical fin - centered between the tip fins - to improve control characteristics. The "M" refers to "manned" and "F" refers to "flight" version.
Early flight testing of the M2-F1 and M2-F2 lifting body reentry configurations had validated the concept of piloted lifting body reentry from space. When the M2-F2 crashed on May 10, 1967, valuable information had already been obtained and was contributing to new designs.
NASA pilots said the M2-F2 had lateral control problems, so when the M2-F2 was rebuilt at Northrop and redesignated the M2-F3, it was modified with an additional third vertical fin - centered between the tip fins - to improve control characteristics.
After a three-year-long redesign and rebuilding effort, the M2-F3 was ready to fly. The May 1967 crash of the M2-F2 had torn off the left fin and landing gear. It had also damaged the external skin and internal structure. Flight Research Center engineers worked with Ames Research Center and the Air Force in redesigning the vehicle with a center fin to provide greater stability. At first, it seemed that the vehicle had been irreparably damaged, but the original manufacturer, Northrop, did the repair work and returned the redesigned M2-F3 with a center fin for stability to the FRC.
The Northrop M2-F2 was a heavyweight lifting body based on studies at NASA's Ames and Langley research centers and built by the Northrop Corporation in 1966.
The success of Dryden's M2-F1 program led to NASA's development and construction of two heavyweight lifting bodies based on studies at NASA's Ames and Langley research centers—the M2-F2 and the HL-10, both built by the Northrop Corporation. The "M" refers to "manned" and "F" refers to "flight" version. "HL" comes from "horizontal landing" and 10 is for the tenth lifting body model to be investigated by Langley.
The M2-F2 made its first captive flight (attached to the B-52 carrier aircraft throughout the flight) on March 23, 1966.
The first flight of the M2-F2 - which looked much like the M2-F1 - was on July 12, 1966. Milton O. Thompson was the pilot.
By then, the same B-52 used to air launch the famed X-15 rocket research aircraft was modified to also carry the lifting bodies. Thompson was dropped from the B-52's wing pylon mount at an altitude of 45,000 feet (13,700 m) on that maiden glide flight. He reached a gliding speed of about 450 miles per hour (720 km/h).
