First Flight #14: AirDropper

Summary

The current implementation does not have reentrancy guards. While the claimFees() and claim() functions don't seem to directly be at risk due to their straightforward logic and the use of the safeTransfer() from OpenZeppelin (which mitigates some of these concerns), it's generally good practice to prevent reentrancy for any state-changing external functions.

Recommendations

Use the nonReentrant modifier from OpenZeppelin's ReentrancyGuard utility, especially in functions dealing with token transfers or ether withdrawals.
