Very smoky departure ! B-52 Stratofortress impressive take-off – B-52s left a trail of black smoke during take-off. After over 60 years, it’s still the primary bomber of the United States. Yes, it had a lot of upgrades over the years, but the airframes are still flying although out of 744 planes built, the last on left the assembly line in 1962.
The eight engines are very “old tech” and inefficient. If you look at pictures of most early jet aircraft, both large and small, you will see that they are very smoky. Modern engines burn fuel more efficiently and emit a far smaller amount of unburned hydrocarbons…
