Since the early 1950s on conventional carriers it has been the practice to recover aircraft at an angle to port of the axial line of the ship. The primary function of this angled deck is to allow aircraft that miss the arresting wires, referred to as a bolter, to become airborne again without the risk of hitting aircraft parked forward. The angled deck allows the installation of one or two "waist" catapults in addition to the two bow cats. An angled deck also improves launch and recovery cycle flexibility with the option of simultaneous launching and recovery of aircraft.
When did conventional carriers start recovering aircraft at an angle to port of the axial line of the ship?
early 1950s

During their investigation of Noriega, Kerry's staff found reason to believe that the Pakistan-based Bank of Credit and Commerce International (BCCI) had facilitated Noriega's drug trafficking and money laundering. This led to a separate inquiry into BCCI, and as a result, banking regulators shut down BCCI in 1991. In December 1992, Kerry and Senator Hank Brown, a Republican from Colorado, released The BCCI Affair, a report on the BCCI scandal. The report showed that the bank was crooked and was working with terrorists, including Abu Nidal. It blasted the Department of Justice, the Department of the Treasury, the Customs Service, the Federal Reserve Bank, as well as influential lobbyists and the CIA.
When was BCCI shut down?
1991

Unlike animals, many plant cells, particularly those of the parenchyma, do not terminally differentiate, remaining totipotent with the ability to give rise to a new individual plant. Exceptions include highly lignified cells, the sclerenchyma and xylem which are dead at maturity, and the phloem sieve tubes which lack nuclei. While plants use many of the same epigenetic mechanisms as animals, such as chromatin remodeling, an alternative hypothesis is that plants set their gene expression patterns using positional information from the environment and surrounding cells to determine their developmental fate.
Why do phloem sieve tubes stop forming?
lack nuclei
